Set of seven tombs known as “Mámoas da Cruz”, of which only three are currently preserved. “Mámoa da Cruz”, the mound of earth cannot be fully appreciated, and the five orthostats protruding from the chamber and the moved roof slab can be glimpsed. In this slab, there is a hole where it is believed that at some point a cross might have been nailed, hence its name. It was recognized by the Department of Culture of the Xunta de Galicia in 2011. Coordinates: 42º42’55.4”N 8º01’58.7”W “Altar of the Sun”, the name by which it is known to the locals, corresponds to an enclosed area of 7 orthostats and is presided over by a large stone with two circular-shaped holes oriented to the east. It was declared a BIC as a historical artistic monument in 1974. Coordinates: 42º42’52.5”N 8º01’56.6”W “Mámoa do Cruzamento”, so called because it is right at the entrance junction to Alperiz, on the edge of the road. One of the preserved orthostats stands 1.5 meters high and a carving with serpentine motifs, oriented to the east, can be seen. Coordinates: 42º42’51.5”N 8º01’59.2”W There are two more tombs located in the area known as “Zarra do Canle” that are also preserved. All of them belong to the Neolithic period and were looted, like most of those existing in Galicia, after the license granted by Felipe III to Vázquez de Orxas in 1609, to recover the possible treasures inside for the Royal Treasury, although many of them were looted by peasants driven by the “gold fever” created.
