Castell de Torrent de Cinca dominates a small plateau above the Huesca town of Torrente de Cinca in Aragon. Originally a Muslim settlement dating to 1100, the castle was conquered by Christian forces in 1149 and subsequently controlled by the military Order of the Hospital. The ruins retain irregular rectangular walls with preserved corner towers built in fine ashlar masonry, offering glimpses of medieval Aragonese fortification techniques. Designated as Cultural Heritage of Interest, the remains sit at the town's summit and serve as a testament to centuries of strategic military occupation and the diverse cultural influences that shaped the region's defensive architecture.
