The dolmen of Pedra Moura is one of the largest in Galicia. This ancient funerary monument dates back millennia. The history goes back to between 3,500 and 2,700 BC, during the peak of the megalithic culture. Today, it only preserves five of the seven corners that originally constituted it. Legend has it that the stones that form this dolmen were carried by a woman’s nail from the Calvelo hill, while they were lying on the rock and carrying a child’s nail. It is located in the interior of the town, in the parish of Aldemunde, the smallest in Carballo, in an area of great landscape and ecological interest. Nearby, we reach the Aldemunde castro and, in the same parish, a natural space of great value, the Ribeira da Pena, one of the most important native forests of the Costa da Morte.
