Castle of Doiras Monument · Cervantes, Ancares, Lugo The castelo de Doiras, also called Castelo da Ferrería, is a medieval fortification built on a crag next to the Cancelada river, in the parish of Vilarello in the Lugo municipality of Cervantes. Built in the 15th century by Paio Guindós to defend the entrance to the Way of Saint James in Galicia, it is possibly the best-known monument of the serra dos Ancares; it belonged to the counts of Grajal de Campos and the Duke of Sexto, and passed through several owners before the municipality of Cervantes, together with the Diputación de Lugo, bought it in 2024. The enclosure, rectangular in plan with seven towers, preserves a fourteen-metre keep with rooms holding deteriorated fresco paintings. It was declared Bien de Interés Cultural (Spain's highest level of heritage protection) on 17 October 1994. Photo: SanchoPanzaXXI (CC BY-SA 3.0) What to see and do in Cervantes
