Dug out of the side of a rocky outcrop.
These are two prehistoric tombs. Externally, it has a small access door which leads into two low, interconnecting rooms.
At the top of the hill, for those who want to climb it, there are some low remains of the single-tower Nuraghe Ordari.
On the trunk road Bortigali – Silanus, no more than 2 km from the eastern outskirts of Borigali and no more than 500 from the remains of the S. Martino church, the access door to the domus I is clearly visible. Leave your car by the side of the road and climb up the hill for about 40 metres. The domus II is further north behind the ridge.
