Castelo de Vimianzo stands as one of Galicia's best-preserved medieval castles, dating from the 13th century when members of the Mariño family began construction under royal charter from King Alfonso IX. Built with almost two-meter-thick walls surrounding a polygonal design featuring four towers and an internal arms courtyard, the fortress withstood numerous attacks during the Irmandiñas Wars, protected by its surrounding moat and drawbridge. Following its destruction by the Irmandinos in 1467, Archbishop Fonseca ordered its reconstruction, and it subsequently served as the residence of the Counts of Altamira for centuries. Now under provincial government stewardship, the castle houses a notable ethnographic museum displaying regional craft specialties including stonework, ceramics, lace, baskets, and traditional linens, providing insight into Galician cultural heritage and medieval defensive architecture.
