[1] The Anta is hidden by a clump of trees about 100 metres to the south of the Cave of Salemas.

Although probably identified by the 19th-century Portuguese archaeologist, Carlos Ribeiro, it was first studied and drawn on 17 January 1944 by the German archaeologists, Georg and Vera Leisner, but no excavations were carried out until November 1959 when Vera Leisner and O. V. Ferreira made some limited excavations and corrected the previous plan.

Five limestone slabs of the Late Cretaceous epoch survive on the site, one of which is believed to have been the roof of the tomb.

Although further research has yet to be carried out, other archaeologists believe that further excavation could result in the discovery of an access corridor.

These items are kept at Lisbon’s Geological Museum (Museu Geológico).
