Castello di Quirra, Medieval castle in Villaputzu, Italy.

Castello di Quirra is a medieval fortress situated on a hilltop overlooking the Gulf of Villaputzu. The structure features defensive walls, several towers, and two cisterns that stored water for those living inside.

Built in the 12th century by the judges of Cagliari on Monte Cudias to guard the border with the Judicate of Gallura, the castle was occupied by the Aragonese in 1324. It was later a theatre of clashes between the Kingdom of Sardinia and the Judicate of Arborea, and from 1475 it belonged to the Crown of Aragon.

The castle served as a power center for the noble families who ruled this region during medieval times. Walking through its remains shows how important this place was for controlling the surrounding lands.

Reaching the castle requires walking uphill from the old SS 125 road, a journey of about twenty minutes on foot. Proper hiking shoes and some stamina help make the climb manageable.

The castle is linked to the legend of Violante Carroz, a noblewoman from this era whose name carries dark tales. Stories speak of hidden treasures in nearby caves that supposedly remain undiscovered to this day.
