Large dolmen, made up of nine stanchions, with an access corridor that distinguishes itself from the funeral chamber in plan and elevation, and which originally was composed of three stalks on each side. In its interior are still visible engravings, that we must conserve. The deck of the dolmen is broken, missing those of the corridor and the slab that would act as entrance door, which was accessed by an open space.
