Hirumugarrieta is a megalithic station located in the pastoral station of Artxanda, in the mountain range that surrounds Bilbao, near Mount Avril. The dolmen has a rectangular chamber. Surrounding it was the galgal composed of slabs folded towards the center of the funerary monument. It has been recently excavated, so this monument constitutes a starting point for the study of the cultural manifestations of the Bronze Age of the Artxanda pastoral station, also allowing analogies and differences to be established with other pastoral stations in the territory.
