Granite stone that was used to mark boundaries in mediaeval times. Located in the village of A Agrela, in Lampai, it is a vertically set granite stone, with a visible height of 133 cm, and a width of 50 cm at the base and 35 cm at the top, and a maximum thickness of 20 cm, fairly regular throughout. Such an even finish throughout the stone, with very clear traces of fairly old fracture, along with its placement in a pre-eminent position in relation to a broad gateway, and the presence of an engraving on the south face, would seem to point to the possibility that it is a mediaeval marker stone, which, like the Porto Marker Stone in Lampai, would have demarcated a large tract of land that in 1156, the Emperor Alfonso VII and much of the aristocracy and the Church of the Crown of Castile bequeathed to Sancho Eanes, a commoner, as a sign of their gratitude for his role in battle during the Reconquest.
