21 Castles In Sardinia That Are Absolutely Captivating

There are dozens of (88 to be precise) medieval fortresses and castles in Sardinia, most built between the 11th and 14th centuries during the period of the Judicates and later Aragonese rule, and reflecting the complicated history of Sardinia. Many survive only as ruins, but several are still well preserved and open to visitors.

I was born and raised in Sardinia and still live on the island, and over the years, I’ve visited many of these castles while exploring different parts of Sardinia. Some stand inside historic towns, others sit on isolated hilltops with wide views over the surrounding countryside.

This guide covers the most interesting castles in Sardinia to visit, from scenic ruins such as Acquafredda to well-preserved fortresses like the one in Sanluri and the Castello della Fava. If you enjoy history, viewpoints, legends, and places that reveal a different side of the island, visiting a castle is one of the most interesting things to do in Sardinia beyond its stunning beaches.

Good to know: There used to be more castles in Sardinia (for example, there was one in the historic center of Sassari, which was demolished in the late 19th century). While we know of their existence, there are no ruins left to visit. The ones I list here can all be visited – though some are in a better state than others.

Why Sardinian Castles Look Different From Other Italian Castles

Castles in Sardinia often look different from the large stone fortresses seen in mainland Italy. Many are just ruins on hilltops or isolated ridges, with only fragments of walls or towers still visible.

This is partly because most Sardinian castles were built for military control rather than royal residence. They were used to monitor territory, protect borders, and oversee important routes across the island.

As a result, many were constructed in strategic but remote locations, often on hills where defenders could spot enemies approaching from a distance.

Over time, several castles lost their military importance and were gradually abandoned. For this reason, many collapsed, and today there isn’t much to see other than ruins.

How Many Castles Are There In Sardinia?

Historians estimate that more than 80 castles once existed in Sardinia, most built between the 11th and 14th centuries. These fortifications played an important role during Sardinia’s medieval period, when the island was divided into four independent kingdoms known as the Judicates: Cagliari, Arborea, Torres, and Gallura.

Many castles were constructed to defend strategic locations, such as mountain passes, fertile plains, and important trade routes. Later, as outside powers became involved in Sardinian politics, the Pisans, Genoese, and eventually the Aragonese reinforced or expanded several of these fortresses to strengthen their control over the island.

Today, the condition of castles in Sardinia varies widely. Some, such as Sanluri Castle, remain well preserved and host museums or exhibitions. Others survive mainly as ruins on hilltops and rocky ridges, where fragments of walls and towers still mark the original defensive structures.

All of them are worth visiting, but if you have limited time on the island...

Which Castles In Sardinia Are Most Worth Visiting?

Sardinia has dozens of castles and ruins, but only a handful are truly essential stops for most travelers. If you only plan to visit one or two during your time in Sardinia, these castles offer the best combination of history, scenery, and accessibility:

• Castello di Sanluri – the most complete medieval castle in Sardinia and one of the easiest to visit, thanks to its museum and preserved interiors.
• Castelsardo Castle – a fortress inside one of the island’s most scenic coastal towns, with sweeping views over the sea.
• Castello della Fava (Posada) – a striking hilltop tower rising above the historic village of Posada.
• Castello di Acquafredda – dramatic ruins on a volcanic hill in southern Sardinia, known for panoramic views of the surrounding countryside.
• Malaspina Castle (Bosa) – an impressive fortress overlooking the colorful riverside town of Bosa.

If you are exploring the island for the first time, visiting two or three of these castles will give you a good sense of Sardinia’s medieval history.

Quick Comparison Table

Castles In Southern Sardinia

Castello di Acquafredda – Siliqua

• Location: Siliqua (about 50 km northwest of Cagliari)
• State: ruins on a volcanic hill
• Best for: panoramic views and medieval history
• Visit time: 45–60 minutes
• Good stop if you are visiting: Iglesias, or the Sulcis region, you can also visit on the way to or back from Porto Pino Beach

Aquafredda is one of the most famous castles in Sardinia.

It also goes by the name of Castello del Conte Ugolino della Gherardesca. The name refers to the same Ugolino, the Tuscan count mentioned in the Divine Comedy written by Dante, who resided in the castle for years.

The Acquafredda name comes from the spring flowing from the rocks right on the hillside of the castle.

Today, the Castle of Acquafredda is still a stunning monument sitting atop a hill of volcanic origins in Siliqua, a small town in the Sulcis region of South Sardinia that’s easy to visit on day trips from Cagliari.

Here in the southwest of Sardinia, from sunrise to sunset, you can watch the shadow of this castle shrink and grow along the valley.

On a clear day, the views from the castle span all the way to Cagliari.

The castle is located about 4 km (2.5 miles) from the center of Siliqua. It is open daily, and there is a small fee to visit. You can also join one of the guided tours such as this one that depart regularly from the castle itself.

Make sure to read my posts, A Useful Guide To The Castello Di Acquafredda, and A Guide To Siliqua, for more information on this interesting castle.

Castello San Michele – Cagliari

• Location: Cagliari
• State: restored castle with exhibition space
• Best for: views over the city and cultural exhibitions
• Visit time: 30–45 minutes
• Good stop if you are visiting: Cagliari

This is one of the castles in Sardinia I have the fondest memories of. I was just a child the first time I visited (it must have been 1987 or 1988). Back then, it was just ruins and it was sadly used as a refuge by people with a drugs addiction.

Much has been done to restore the castle and bring it back to its original glory since my first visit.

The castle is situated right on the hill of San Michele, a lesser-visited area of Cagliari, and it’s surrounded by one of the most beautiful city parks.

It was built in the 10th century as a fort and then it became the private residence of the Carroz, a noble Aragonese family. It was also used as a place of protection and defense from enemies. More than once throughout the centuries, the castle also served as a hospital.

Now, the Castle of San Michele is privately owned. Surrounded by a pine forest, it has a lovely garden that’s a pleasant place to wander around and take in the views of the city. Locals (including myself) go there to run, walk their dogs, or just for sunset views.

The Castle of San Michele is currently used to host arts and cultural events and exhibits, which vary on a regular basis.

You will have to pay a small admission fee to visit.

Castello d’Eleonora d’Arborea – Sanluri

• Location: Sanluri (South Sardinia)
• State: well-preserved medieval castle
• Best for: museum visit and medieval architecture
• Visit time: 60–90 minutes
• Good stop if you are visiting: Barumini, Su Nuraxi, and the Giara Plateau

Out of the more than 80 castles in Sardinia, the Castello d’Eleonora d’Arborea (also known as Castello di Sanluri) is the only one still habitable! This castle was built before the 14th century and is situated in Sanluri, roughly a 35-minute drive north of Cagliari and ideal for a day trip from the capital.

The castle is visually arresting. Each side of the quadrangular castle stands 26 meters (85.3 feet) high and has four crenelated towers. The inside of the castle is a testament to Sardinia’s past.

The first testimony of the castle is from 1355, in a document that suggests that King Peter of Aragon wished to do some renovation works on the castle (this means the castle dates before then).

The castle was finally abandoned by the Spaniards in 1839 when they left Sardinia, and it was acquired by the Villasanta family in 1920.

There are multiple rooms to visit, styled in grand renaissance decor and with beautiful antique furnishings. The castle has been turned into a museum and has one room entirely dedicated to WWI, one dedicated to wax models, and paintings.

There’s only one resident in the castle – Piuma, a white cat that decided this would be her home.

There is a small admission fee to visit this castle, which includes a guided tour of about one hour. I recommend pairing your visit with a wine tasting at Cantine Su’ Entu (one of the best wineries in Sardinia) and lunch or dinner at Coxinendi, one of my favorite restaurants in Sardinia located just in front of the castle.

I have written a full Sanluri Guide that will help you plan a fun day trip to this small town near Cagliari.

Castello Siviller – Villasor

• Location: Villasor (Campidano plain)
• State: well-preserved fortress-palace
• Best for: architecture and historical significance
• Visit time: 30–45 minutes
• Good stop if you are visiting: Cagliari or southern Sardinia

The Castello Siviller in Villasor is an Aragonese Gothic castle, built in the early 1400s in the south of Sardinia. Unlike most of the Sardinian castles on my list, this one is not built on a hillside, but instead in the historic center of the town of Villasor.

As history shows, the castle was built by Giovanni Siviller upon the wishes of King Alfonso of Aragon, who wished to repopulate the area of Villa di Sor (now called Villasor), mostly abandoned after the continued conflicts between the Kingdom of Arborea and the Aragonese.

Much like other Sardinian castles, Castello Siviller changed properties a few times in its history and became property of the Pisan rulers of Sardinia, then the Kingdom of Arborea and of the Aragonese. Eventually, the castle became property of the Alagon family when Salvatore Alagon of Oristano married into the Siviller.

Later in its history, the castle was used as a prison and as barracks. It is currently the property of the municipality of Villasor.

As the Castle of Villasor is still in excellent condition, it hosts arts and cultural events periodically throughout the year, especially in its courtyards. It was built as a complex with an internal and external courtyard, with two stories and many wings.

Its external appearance is still exceptionally medieval; however, the internal parts have been modified and updated dozens of times throughout the centuries.

Guided tours of the castle are available if booked in advance. You will have to send your request either via email to [email protected].

Castello di Baratuli – Monastir

• Location: Monastir (near Cagliari)
• State: ruins
• Best for: medieval history and a quiet countryside setting
• Visit time: 20–30 minutes
• Good stop if you are visiting: Cagliari or southern Sardinia, and the domus de janas of Monte Zara

The Castello di Baratuli was built over a previous Nuragic settlement on top of Mount Oladri.

Situated in Monastir in the south of Sardinia (very easy to reach from Cagliari by car), the castle was constructed in the middle of the 12th century; however, it was destroyed in 1308 by the Pisans. All that’s left now is lonesome rubble.

In recent years, the Castle of Baratuli has been the site of many excavations and restorations.

When you visit the castle today, you’ll only see the base of the castle – stones that reach no higher than a couple of meters. However, the hike up to see the ruins will provide you with romantic and sweeping views of the Sardinian countryside below. It’s well worth the trip up!

There is no admission fee to visit this castle.

Castello Salvaterra – Iglesias

• Location: Iglesias (Southwest Sardinia)
• State: restored structure within the historic town
• Best for: views over Iglesias and medieval town history
• Visit time: 30–45 minutes
• Good stop if you are visiting: Iglesias or the Sulcis mining region

The Castle of Salvaterra – also known as the Castle of San Guantino – was built in 1258 for Count Ugolino della Gherardesca.

Sweeping upward on the Salvaterra hill in Iglesias, it stands in an elevated position over the rest of the town, something which allowed it to protect the city and communicate with other castles built by the Republic of Pisa – namely Villamassargia Castle, Acquafredda Castle, and San Michele Castle in Cagliari.

The castle remained in use until the end of the 19th century, when it lost its military purpose and was joined to a villa and glass factory next door.

To visit the castle, you’ll have to book a guided tour via the Associazione Balestrieri Iglesias by calling +393519783566.

I have written a full Guide To Iglesias that includes even more attractions in this unique town in South Sardinia.

Castello di Gioiosa Guardia – Villamassargia

• Location: Villamassargia (Sulcis region)
• State: ruins on a hill
• Best for: hiking and scenic views
• Visit time: 45–60 minutes
• Good stop if you are visiting: Iglesias or Sulcis

The Castle of Gioiosa Guardia is located in Villamassargia, in South Sardinia. The construction of this castle can be dated to the 13th century.

The castle sits on a hill at 396 meters (almost 1,300 feet) above sea level, and like the Acquafredda Castle, it was the residence of Ugolino della Gherardesca.

After becoming the property of Guelfo, his son, and then of Brancaleone Doria (husband of Sardinia’s most famous ruler, Eleonora d’Arborea), the castle was eventually seized by the Aragonese.

It was eventually abandoned between the end of the 14th century and the beginning of the 15th century, for unknown reasons.

Today, a few bits of the castle are still visible. These include a cistern, a tower, and what appears to have been a terrace.

The Castle is actually located on private land, and, unfortunately, there is no available information regarding the opening times and fees. Your best bet is to call the Comune di Villamassargia at +3907817580204 and enquire.

Castello di Monreale – Sardara

• Location: Sardara (Marmilla region)
• State: ruins
• Best for: views over the Marmilla countryside
• Visit time: 30–45 minutes
• Good stop if you are visiting: Sardara or Barumini

The Castle of Monreale sits atop a 280-meter hill above sea level (that’s over 918 feet), in the Campidano plain. From this castle, you’ll have a view that reaches all the way to Cagliari.

The castle dates from the 13th century, when it was built by the governor of Arborea. In its time, the castle was used as a refuge for the troops defeated in the Battle of Sanluri. Later on in the late 15th century, it was used by the Aragonese troops.

Built in a pentagonal shape, the Castle of Monreale was once encompassed by a few round and square towers. Today, only the external walls and the ground floor are visible. The ruins of the village that once lay at the foot of the hill can still be seen and explored.

Finally, the Castle of Monreale is one of the best spots in Sardinia to catch a beautiful sunset.

The castle is located a bit outside of Sardara. It is free to visit.

Castello di Quirra – Villaputzu

• Location: Villaputzu (southeast Sardinia)
• State: ruins
• Best for: history and panoramic views
• Visit time: 45 minutes to one hour, including the walk up the hill
• Good stop if you are visiting: Costa Rei or southeast Sardinia

The Castle of Quirra sits above Cala Murtas Beach, which is an easy drive from either Villaputzu and neighboring Muravera, and an easy day trip from Costa Rei. It’s one of the lesser-known castles in Sardinia, and chances are that if you visit, you’ll have it all to yourself – at least that was the case for me when I visited.

The castle is located at 296 meters (971 feet) above sea level, so you can expect magnificent coastal views from there. It was built in the first half of the 13th century and occupied by the Pisans until 1324 – that’s when the Aragonese, led by Francisco Carroz, conquered the castle. 

While the Castle of Quirra once stood in splendor and glory, today, only the perimeter walls are left. 

The castle is located outside of Villaputzu, a 25-minute drive. It is free to access. To get there, you will have to follow a steep uphill road from the intersection where you can park your car.

Castello Orguglioso o di Sassai – Silius

• Location: Silius (Gerrei region)
• State: ruins
• Best for: remote scenery and hiking
• Visit time: 45–60 minutes
• Good stop if you are visiting: southeast Sardinia

The Castello Orguglioso o di Sassai is lauded for its position in a highly strategic location, protruding from the hillside in such a way that it can monitor and guard the territories of Silius, San Nicolò Gerrei, Ballao, and Goni.

Erected in the 13th century upon orders of the Judicate (Reign) of Cagliari, which back then was controlled by Pisa, the Castello Orguglioso only remained active for roughly 100 years, and for its last 30 years it was under Spanish Rule.

Its main purpose was to defend the borders of the Judicate from enemies coming from other judicates on the island. When Sardinia became entirely controlled by the Spaniards, this and other castles located along the borders of the judicates lost their purpose and were abandoned.

While much of the castle has fallen into disrepair over the centuries, an impressive stone structure remains relatively intact thanks to many restorations. Several rooms have been identified in the castle, including what appears to have been used as a prison, and one that was likely a kitchen since an oven was found there.

A legend says that the Countess of Sassai died under a collapse of walls during a siege and still haunts the castle, crying among the ruins.

Should you want to visit the castle, you will have to call in advance. The number to call is +39070959006.

Castles In Central Sardinia

Castello di Burgos – Burgos

• Location: Burgos (central Sardinia)
• State: ruins with partially preserved structures
• Best for: dramatic hilltop setting and views
• Visit time: 30–45 minutes
• Good stop if you are visiting: Villa Piercy and Foresta Burgos near Bolotana

The Castle of Burgos dwells right in the heart of Sardinia. It proudly stands atop of a 647-meter (almost 2,123 feet) high granite hillside. This was one of the safest and most protected fortresses in Sardinia back in the day. It was used as a shelter during wars or battles.

I visited on an Easter Monday a couple of years ago, when I was actually meant to visit Villa Piercy in Bolotana, nearby. As that was too crowded and impossible to get in, we opted for the castle. It was pleasantly quiet, not to mention the views of the castle from the road leading to the village, and the views from the castle are breathtaking.

The castle was probably built in the mid-12th century by Gonario I of Torres. It has three walls created with granite blocks and stones. The walls were later reinforced with bricks and mortar.

Located at its center, there’s a courtyard and a tower (built in limestone and red vulcanite). The tower consists of two floors, and it’s 16 meters (52.5 feet) high. The courtyard also has a cistern for water collection. There are also the ruins of a dwelling that was probably used by soldiers or servants.

There is a small admission fee to visit the castle. You can get a combined ticket to also visit the nearby Castles of Sardinia museum.

You should also read my post, The Ultimate Guide To Burgos, Sardinia, for more tips on nearby attractions.

Castello di Barumele – Ales

• Location: Ales (Marmilla region)
• State: ruins
• Best for: history and countryside scenery
• Visit time: 20–30 minutes
• Good stop if you are visiting: Marmilla villages, Barumini

Like many other castles on the island, the Castello di Ales goes by another name – the Barumele Castle. This medieval castle was built on the remnants of a Byzantine fortress and is one of the most intriguing castles in Sardinia.

Today, it appears to us as a single, solitary tower, reaching just a few meters in height. This is actually part of a decagonal tower that is quite impressive architecturally.

Moreover, there are just a few stones scattered around the hilltop that are the remains of the perimeter wall. While you don’t really picture a wall when you see a smattering of stones, they are reminders of the salient wall that used to be there.

The castle is located a 4-minute drive south of Ales, a small town a 40-minute drive from Oristano, and about one hour from Cagliari. It’s just a 30-minute drive from Barumini, so it’s easy to weave it into your itinerary if you intend to visit Su Nuraxi (one of the most famous archaeological sites in Sardinia) and the nearby Giara Plateau. It is free to access.

Castello di Medusa – Lotzorai

• Location: Lotzorai (Ogliastra)
• State: ruins
• Best for: unusual setting in the countryside
• Visit time: 20–30 minutes
• Good stop if you are visiting: the Baunei Coast

Surging upward from central Sardinia’s verdant landscape rests the ruins of a medieval castle, likely built on the ruins of a nuragic structure that later housed a Punic and Roman temple.

The Castle of Medusa is encompassed by hills, ravines, and stunning woodland. There are even limestone cliffs riddled with caves.

Throughout its history, it changed owners several times, becoming Pisan, then owned by the Judicate of Ogliastra first, and then by the Judicate of Gallura in Northern Sardinia. It then became Genoese, and finally, in 1308, it became Pisan again before falling into the hands of the Aragonese in 1324.

According to historic documents, it was a fairly big castle with two towers and a central keep. Today, the castle is mostly in ruins and surrounded by thick vegetation.

The castle is named after an ancient Sardinian pagan goddess called Medusa, as well as a Princess Medusa. 

According to legend, Phorco, a man who traveled from Africa, built this castle so he could proclaim himself the king of all of Sardinia. He had a daughter named Medusa, who happened to be a witch who could manipulate the world with magic. When she was killed, her ghost could turn those who came to steal her treasure into stone.

Apparently, the Castle of Medusa was filled with ghosts, demons, and treasures. Locals still believe there is treasure to be found on the castle grounds, but they are protected by deadly demon flies.

The castle is located within easy walking distance from the center of Lotzorai, which is about halfway between Tortolì and Santa Maria Navarrese (the best access point to the Baunei Coast). Access is free.

A castle by the same name exists in Samugheo, also in Sardinia.

Castello Giudicale – Las Plassas

• Location: Las Plassas (Marmilla)
• State: ruins with a museum nearby
• Best for: archaeology and medieval history
• Visit time: 30–45 minutes
• Good stop if you are visiting: Barumini

In the south of Sardinia in the Marmilla region, not far from Barumini, home to Su Nuraxi, one of the most famous nuraghe in Sardinia, lies one of the lesser-known castles in Sardinia.

The Castello Giudicale – also known as the Marmilla Castle – is located on top of a nearly perfect conical hill at 294 meters (almost 899 feet) above sea level.

While the village of Las Plassas is one of the smallest villages in Sardinia, with only 250 inhabitants, the castle makes it an interesting destination that’s easy to reach on a day trip from Cagliari (you can pair the visit with that of the nuraghe in Barumini and of the wildlife haven of the Giara Plateau).

The castle was built in 1172 and belonged to the Judicate of Arborea, and like many other castles in Sardinia it had defensive functions. After the Battle of Sanluri in 1409, the castle became property of the Aragonese.

It remained in use during feudal times and was used as a prison until the 19th century.

While it’s much in ruins, you can still see the main tower, the perimeter and the internal walls, as well as a large cistern.

The castle is located a 2-minute drive (or 20 minutes’ walk) from the center of Las Plassas. Access is free.

Castello Ezzu (Castello del Montiferro) – Cuglieri

• Location: Cuglieri (Montiferru region)
• State: ruins
• Best for: views over the western coast
• Visit time: 30–45 minutes
• Good stop if you are visiting: Bosa

The Castello del Montiferro – often referred to as the Casteddu Ezzu – translates to the “Old Castle” in the language of Sardinia. It’s located in Cuglieri, a 30-minute drive south of Bosa. It has been left in rubble and wreckage, with just enough stones remaining that you can see the shell of a castle.

The castle likely dates from before 1196 (that’s when it’s first mentioned in a document), and it belonged to the Judicate of Arborea during the 13th century. When the Aragonese arrived in the 15th century, it was given to the Spanish Zatrillas family.

An intriguing story took place in the castle, where Donna Francesca, countess of Cuglieri and wife of the Marquis of Laconi, was accused of killing her husband together with her lover. She found refuge in the castle, but when she discovered that a commissioner was on his way to arrest her, she abandoned her shelter and never came back.

Later on, the Aragonese confiscated the castle, which was sold to a nobleman from Cagliari who soon abandoned it.

Legend has it that the castle is haunted by two ghosts: in the underground rooms, a noble child and his nanny stayed hidden while under siege for days – until they died. On windy nights, legend has it that you can hear lullabies being sung to the child.

There are the leftovers of towers, walls, and subterranean rooms. From the castle itself, you can take in incredible panoramic views of Sardinia’s western coastline below.

The castle is located about a 7-minute drive out of Cuglieri. Access is free.

My post, What To See In Cuglieri, highlights other attractions in the area.

Castello di Aymerich – Laconi

• Location: Laconi (central Sardinia)
• State: ruins in a wooded park area
• Best for: nature walks and history
• Visit time: 30–45 minutes (including the walk to get there)
• Good stop if you are visiting: Laconi or central Sardinia

While only a few ruins remain of the Castle of Aymerich, you should still make it a point to visit. First of all, Laconi is one of the most pleasant small towns in Sardinia – completely off the beaten path, about a 1.5-hour drive from Cagliari.

As the name suggests, the castle belonged to the Aymerich family, a Catalan family that settled in this part of Sardinia in the 14th century. The castle dates from the 12th century – so it was built before the arrival of the Aymerich family.

The castle stands on the higher ground. What remains is just parts of the walls, a room with seating, and a beautiful window overlooking the Aymerich Park. This is one of the most beautiful parks in Sardinia, and a great place to visit if you are in Sardinia in October (that’s exactly when I visited) to experience the foliage season.

Inside the park, there are streams, small waterfalls, and an abundance of trails.

Visiting the park (and the castle) is free.

I have written a detailed Guide To The Places To Visit In Laconi that will inspire you to visit.

Castello di Pontes – Galtellì

• Location: Galtellì (east Sardinia)
• State: ruins
• Best for: views over the Cedrino valley
• Visit time: 30–45 minutes
• Good stop if you are visiting: Orosei or the Gulf of Orosei

The Castle of Pontes dwells on the eastern coast of Sardinia, near the central region, and it’s located at the foot of Mount Tuttavista in Galtellì, a small town about a 20- minute drive from the more popular Dorgali.

Archeologists date the origin of this castle to 1070, when it was built on top of older Roman fortification. Back then, Galtellì was an important town of the Judicate of Gallura – when that reign finished, it was conquered by the Aragonese.

The castle was inhabited up until the 15th century: the last owner was Baron Guiso, around whose figure there are several legends, including one that sees his ghost roaming the ruins at night.

Today, you can still see one of the towers and admire the remains of an underground cistern. From the castle, you can enjoy impressive views of the Cedrino Valley.

The castle is located a 3-minute drive outside of Galtellì. For information about visiting, get in touch with the tourism information office at +39 0784 90150.

My post What To See In Galtellì includes more tips on places to visit in this pleasant small town.

Castles In Northern Sardinia

Castello dei Doria – Monteleone Rocca Doria

• Location: Monteleone Rocca Doria (northwest Sardinia)
• State: ruins
• Best for: scenic views and a quiet historic village
• Visit time: 30–45 minutes
• Good stop if you are visiting: Alghero or Sassari

The Castle of Doria is located in Monteleone Rocca Doria, in northwest Sardinia, about half-way between Alghero and Bosa (though beware it’s not on along the beautiful panoramic road – one of the best in Sardinia – most would drive along to reach Bosa). It was commissioned in the late 12th century or early 13th century for the prestigious Doria Family of Genoa.

This family was seeking to consolidate their presence in the northwest of the island. They did so by erecting a network of castles, as well as impressive fortified residences.

It is estimated by archeologists that the fortified wall around the castle continued for nearly 800 meters (that’s almost half a mile) and that there were ten circular towers built for guards to be stationed as lookouts.

The castle fell under siege in the mid-1400s by the Crown of Aragon, and it was destroyed. Today, the Castello dei Doria is in ruins; however, there are still some gorgeous stone walls and an archway to look at.

The castle lies at a minute walk from the tiny village. It is free to visit.

Castello Serravalle (or Malaspina) – Bosa

• Location: Bosa (west Sardinia)
• State: partially preserved castle
• Best for: views over Bosa and the Temo River
• Visit time: 45–60 minutes
• Good stop if you are visiting: Bosa or Alghero

Perched atop the Serravalle hill lies the Castle of Serravalle— also called the Castle of Malaspina—which has protected the village of Bosa since 1112.

It’s one of the most famous castles in Sardinia, not to mention my favorite. I visit any time I am in Bosa, as I love not only the building itself, but also the impressive views you get from it.

Property of the castle changed hands often in the course of its history: initially the residence of the Malaspina family, the castle became property of Pietro Ortis in 1330.

After several renovations, only the walls and towers remain today, as well as some beautiful frescoes that you can see in the Palatine Chapel built in the 14th century during the reign of King Alfonso the Magnanimous (Alfonso V of Aragon).

The view from the top is stunning as well, as this castle was built 81 meters (about 266 feet) above sea level.

The castle is open daily. Opening times vary with the season. There is a small fee to visit.

I wrote a guide on What To See And Do In Bosa Sardinia that will inspire you to spend more time in Sardinia’s prettiest small town.

Castello della Fava – Posada

• Location: Posada (northeast Sardinia)
• State: partially preserved tower and walls
• Best for: views and photography
• Visit time: 30–45 minutes
• Good stop if you are visiting: San Teodoro or Siniscola

The Castle of Fava is one of the best-preserved castles in Sardinia. Lying in the northeast of Sardinia, this medieval fortress sits on a hill looking over the lovely town of Posada. It’s easy to visit if you are basing yourself in San Teodoro (just a 20-minute drive), Budoni, La Caletta (a mere 8-minute drive), and even Orosei.

There is a wonderful story about how the Castle of Fava—named after fava beans— got its name. In the year 1300, a Turkish fleet laid siege on the fortified village of Posada. Once the villagers ran out of food, they fed their last bag of beans to a pigeon. It was done so that no one would fight over the last morsels.

However, the bird couldn’t fly far and actually fell into the enemy’s camp with a swollen and full stomach. The Turkish enemy assumed that the villagers had bountiful resources and could outlast them. So they picked up and left.

Regardless of the name, the Castle of Fava is one of the most beautiful in Sardinia. Constructed out of barely-worked stones, this castle is stately and striking.

Once inside, you can go up the tower for impressive views of the town below, and the hills around it (and the beach) – though I shall warn you, going up that tower isn’t the easiest thing.

There is a small fee to visit the castle.

Castello dei Doria – Chiaramonti

• Location: Chiaramonti (Anglona region)
• State: ruins
• Best for: history and countryside views
• Visit time: 20–30 minutes
• Good stop if you are visiting: northern Sardinia

The Doria contributed to the construction of more castles in Sardinia. The one in Chiaramonti is particularly impressive. The castle is located in the highest part of the village at 465 meters (1,525.5 feet) above sea level.

It was built between the 12th and the 13th century, conquered by the Aragonese in 1348 and once again became property of the Doria in 1350.

The castle then became property of the Archbishop of Arborea, but in 1357 it was once again returned to the Doria: when Matteo Doria died, his brother Brancaleone (married to Eleonora d’Arborea, ruler of the region) inherited the property.

Other attempts to conquer the castle failed and in 1437 it was still property of the Doria family -but when the Doria’s fortunes started fading, the castle was turned into a church and eventually completely abandoned.

The castle is easy to reach on foot from Chiaramonti. It is free to visit.

Castello dei Doria – Castelsardo

• Location: Castelsardo (north Sardinia)
• State: well-preserved castle with a museum
• Best for: history and coastal views
• Visit time: 60 minutes
• Good stop if you are visiting: Castelsardo

The Castle of Doria was constructed in 1102 and has a total of 17 towers. It was built for the Genoese Doria family (yes, the same one that I have already mentioned a few times in this post) and has been perfectly preserved.

Situated in Castelsardo on the northern coast of Sardinia, Castello dei Doria houses the Museum of the Mediterranean Weave, one of the most important museums in Sardinia. It’s a true fairy-tale castle, although there are few ruins left of the fortress.

The infamous tower has been well preserved. It still stands 20 meters (65.5 feet) high and is constructed in a pentagonal layout.

According to local legend, there was a maze of underground tunnels below the castle that were said to be where the Doria family minted coins and stored their gold!

The opening times of the Castello dei Doria in Castelsardo vary seasonally and there is a small admission fee which includes tickets to the museum.

Final Considerations

Most people visit Sardinia in the summer to make the most of the pristine beaches the island has to offer. As I tried to show in this post, there’s more than beaches in Sardinia: should you decide to visit Sardinia in the winter, or come to Sardinia during the autumn months, or even in the spring, you will have a vast choice of things to do.

Castles are scattered across Sardinia, often perched on hilltops, mountain ridges, or overlooking historic villages. Many date back to the medieval period, when they were built to control strategic routes and defend territory.

While some castles, such as Sanluri or Castelsardo, are well preserved and can be visited as museums, many others survive only as ruins. Even so, they are still worth visiting and are fun places to experience for the whole family.

In many cases, castles are also closely connected with historic towns, so it is easy to combine a visit with a walk through the town. Places like Bosa, Posada, and Castelsardo are good examples: in these cases, the castle becomes part of the overall visit.

Many of the castles mentioned in this post are fairly isolated, and you’ll be better off renting a car for your trip to Sardinia to access them.

I always use Discover Cars when renting a car, anywhere in the world. They are the best comparison site for car rental.

If you are interested in history, landscapes, and lesser-known places of Sardinia, exploring a few castles can add an interesting dimension to your trip around the island.
