The smallest of the three dolmens that make up the unit is of the “corridor” type. It is said to date back to about 2000 before Christ.
It is a grave set in a covered gallery, which is formed by a access corridor which in turn is accessed through a door carved out of a monolith. The corridor is perfectly preserved and is formed by eight large stones on the right and seven on the left. The ceiling is made up of seven large slabs, but only four remain in place today. The chamber is formed by five large slabs, four of them are the walls and the other acts as a ridge tile over the corridor.
