This is a ‘pitched type’ nuraghe (a tancato), which consists of two towers of different heights (the keep and the perimeter tower) joined by a rectilinear open courtyard. It was built using large, freshly hewn blocks of stone of volcanic origin arranged in overlapping rows. 

The oldest tower (the keep) is also the tallest, standing at a maximum height of 8.10 metres, and faces northeast with the entrance projecting south-west. The main entrance - a door surmounted by an architrave - is in the central part of the straight wall, leading to a corridor and then into the rectangular inner courtyard.

On the right-hand side is the entrance to the keep, a wide opening with a large lintel and a relieving window located immediately above.

A straight corridor with a pointed ceiling leads to the main chamber. On the right side of the entrance, 14 steps remain of the original spiral staircase leading to two other superimposed chambers, closed with a 'tholos' vault, but now collapsed. The secondary tower, reaching a maximum height of 6.75 metres, is also accessible through a corridor.
