Mina da Parxubeira Monument · Mazaricos, Xallas, A Coruña A passage-grave dolmen, also known as the dolmen de Corveira, located at the site of Estivada Vella, in the parish of San Fins de Eirón (Mazaricos, A Coruña), dated between the 4th and 3rd millennia BC and part of the Sotorraño-Parxubeira-Portocoiro necropolis. Its passage, facing east, retains thirteen orthostats, six in the polygonal chamber and seven in the passage, and was covered by a mound between 19 and 22 metres in diameter with a stone shell. Inside were found flint blades, an arrowhead, bell-beaker pottery and several stone idols, among them incised betyls planted vertically next to the passage, possibly to protect the deceased; the whole grave goods assemblage is kept at the Archaeological Museum of A Coruña.
