Dolmen das Pedras Grandes

The Dolmen das Pedras Grandes is a mass grave consisting of a megalithic burial chamber of polygonal shape and a small corridor-oriented SE. The monument is based on a block of limestone and basalt from the Turonian (from the site), medium size, with the camera originally composed of eight pillars that surrounded a tumulus (or mound) of land predominantly clay. The corridor was composed by two pillars, one on each side of it.
