Castle of Acquafredda, Medieval castle in Siliqua, Italy
Castle of Acquafredda stands in ruins on the summit of a 256 m volcanic hill above the Cixerri valley near Siliqua. Its rough orange, brown and grey stone survives as two separate wall sections at the top, a lower broader one left and a taller narrower one right, with lower fragments and a small arched opening on the left flank. The fort was arranged on three levels: a walled borgo with stables and stores at the base, a three-room barrel-vaulted cistern tower at the middle level, and a U-shaped castle with its guard tower above.
The castle was built during the medieval period as a defensive stronghold to control the Cixerri Valley region. It was eventually abandoned as political changes and shifts in power across Sardinia led people to move away from the area.
The castle served as a working home for residents and military personnel who shared the space over centuries. The layout reveals how people moved between living quarters, storage areas, and defensive positions in their daily routines.
The ruins stand on a volcanic hill 256 m above sea level, reached on foot along natural paths over uneven rock. The site is laid out on three levels, from the base of the hill up to the summit, so allow time for the climb and wear hiking shoes with firm grip.
Excavations at the castle brought to light the remains of three men aged between 34 and 45, buried directly in the bare earth. The find is a concrete trace of those who lived at the fortress, not just of its walls.
