Peripheral containment lithic ring, concentric to the chamber, which is regular polygonal, with six pillars in situ, open to an access corridor composed of 15 pillars, of which 13 in situ, of medium size with a closing slab at the end of the chamber elongated, tending to SUB trapezoidal, with at least 12 pillars in situ preserved on the north side, and medium-sized corridor, perhaps with seven pillars on each side, slightly different in plan and with a height more or less constant relative to the chamber, since the pillar of the transept was deeply buried in the base soil. Access to the interior of the tomb, centered and uncovered, would take place through two spaces: the atrium and the “Intra tomb corridor”

The estate exhumed during the archaeological work is characterized by the presence of geometric microliths and flint blades, quartz crystals, 2 arrowheads also in quartz, 1096 necklace beads, discoidal, in schist, a reddish bead whose material is press is unknown and some ceramic fragments. This artefact package marked by the substantial presence of microliths and blades, shale beads, little pottery and few arrowheads, points to an ancient phase of regional megalithism, perhaps from the beginning of the 4th millennium BC.

This monument is part of the pedestrian route “Rota do Megalithic” (PR5).
