Piloña is a municipality in the province and autonomous community of Asturias, northwestern Spain. Its capital is the town of Infiesto. Piloña is bounded to the north by Villaviciosa and Colunga, to the east by Parres, to the west by Nava and Cabranes, and to the south by Ponga, Caso and Sobrescobio. The area is semi-mountainous with many small, but deep and narrow valleys.HistoryIn prehistoric times Piloña lay along the natural path between Oviedo and Cangas de Onís, in the narrow basin that parallels the coast. Piloña was the largest settlement along that path which connected central Asturias with the Asturian east.Even earlier there were paleolithic settlements in caves in Piloña such as Aviao (Espinaredo) Cave, Collaréu Cave, and La Peña Ferran (Ferran Rock) which were excavated by the Count de la Vega del Sella in the 1920s. There are several sites with paleolithic rock art and Neanderthal remains, most notable perhaps being Sidrón Cave in Borines.During Roman times Beloncio was occupied, and is identified with the town Paelontium, mentioned by Ptolemy as the capital of the Astur tribe known as Lugones. There is also evidence of Roman occupation at Borines.
