The walls are square blocks of local granite; its layout is trapezoidal with three rooms on the ground floor and an east-facing entrance. The building most likely had two floors. In the construction elevation, restored in the 1990s, you can see numerous holes for inserting the wooden beams at the base of the upper storey floor. There is a granite basin in the entrance chamber which possible served as the castle’s water supply. This was destroyed in 1422 by the Catalan-Aragonese.
Follow the country road SP14 Luogosanto-Arzachena to reach the site.
At about 4 km from Luogosanto you will come to the car park with picnic area and the path up to the castle starts from here. Most of it is large stretches of a flight of steps which compensates for the difference in height of about 100 m between the base and top of the hill.
