The Castello di Acquafredda (Acquafredda Castle in English) is one of the most impressive castles in Sardinia. You will find it near Siliqua, a small but pretty town near Cagliari.
The castle isn’t the only attraction in the area, as it was built on a hill of incredible scientific and natural value.
You can visit both the town and the castle/hill on a one-day trip from the capital city, so you won’t need to look for a place to sleep. Just take a picnic as the area is perfect for that.
Visiting Siliqua if you choose to see the castle is a must. The town has some nice churches, worth some pictures (they were all built by the Aragonese and are quite interesting), plus there are some nuraghe ruins and the Zinnigas water springs in the area.
The main attraction, however, remains the Acquafredda Castle overlooking the valley. On a clear day, you can see all the way to Cagliari from the Castle and the views are simply impressive!

The History Of The Castello Di Acquafredda
Legend says that that the castle was built upon orders of Count Ugolino della Gheradesca. He was an Italian noblemen, politician and naval commander accused of treason after many died during the Battle of Meloria in defense of Pisa’s harbor.
He’s the same Conte Ugolino mentioned by Dante Alighieri in his Inferno, to be clear. However, it’s almost certain that the Acquafredda manor was there before he actually arrived. It likely dates from the 13th century.
Once the Guidicati fell, the Pisans – and Count Ugolino with them – came to rule Southern Sardinia, and the castle became part of their properties.
Their kingdom didn’t last long, however, because the island became an Aragonese domain soon afterwards – officially in 1326.
In 1408, all the soldiers still standing guard at the manor left. There was no need to keep troops on an island that was unified under the same ruler.
The area – made up of the village underneath the hill (for servers and lower people), the basin tower where the water was kept and the noble’s residence – was quickly abandoned. The Acquafredda Castle slowly turned into ruins.
There have been several attempts to renew the castle but it degrades quicker than it can be fixed, probably also due to the materials the hill and the castle itself are made of.
The Domo Andesitico
The Domo Andesitico is the hill underneath the castle, a unique ecosystem that’s a safe haven for several rare species – especially birds of prey.
They love to nest here and the fact that they group and lay their eggs in this place is a great indicator of the area’s clean environment (these animals are quite picky when it comes to building a home somewhere!).
You can visit the Domo Andesitico together with the castle, but be careful not to scare the animals. Just bring your binoculars to be able to spot them from a distance!

I am so glad!
As a young serviceman in the United States Air Force I came to Sardinia in 1988. From my kitchen window in the village of Villasor I could see the castle in the far distance. I found it intriguing and went to explore it riding to it by bicycle. I scaled the cliff to reach it going up the wrong side because I didn’t know the easier way was there! I returned several times over two years to explore it and studied what I could learn about it. Along the way I learned Italian and fell in love with the learning. Aquafredda inspired me to go to college where I earned several degrees. That castle and the kind people of Sardinia who taught me Italian changed my life forever and I am very thankful.
