O Castelo de Cira

Spain, Spain

---

O Castelo de Cira refers to the ruins of a medieval fortress located near Cira in Galicia, Spain, likely within the Pontevedra province amid the region's rugged inland terrain.

Dating primarily to the 12th-15th centuries, it served as a noble stronghold during the turbulent Reconquista and Irmandiño revolts, featuring typical Galician stone masonry with defensive towers adapted to local topography for surveillance over valleys and trade routes. 

Though largely deteriorated, the site preserves elements of feudal architecture characteristic of Galicia's pazos and towers, standing as a testament to the area's historical defensive networks now appreciated by hikers and heritage explorers.
