Hillfort of Baroña Nature · Porto do Son, Noia, A Coruña The castro de Baroña stands on a rocky peninsula in the parish of Baroña, in Porto do Son (A Coruña), and was inhabited between the 1st century BC and the 1st century AD. It preserves about twenty circular or oval dwellings spread over four areas, with spaces interpreted as forges, a protected square and a staircase considered one of the best preserved among Galician castros. It was defended by a double wall and a moat four metres wide and three deep that crossed the access isthmus, together with an access tower with a ramp that prevented the passage of carts. Its inhabitants lived off shellfish gathering and fishing, with livestock and acorns, and remains of forging, stone carving and weaving have been found. Excavated in 1933, 1969-1970, 1980-1984, 1985 and since 2012, it was declared Ben de Interese Cultural (Spain's highest level of heritage protection) in 2011.
