The castle is built upon a natural geological formation that previously served as a Roman iron ore extraction point.
It was held by the Knights Templar until the dissolution of the order in the early 14th century.
The name 'Cornatel' likely derives from the rocky 'horn' shape of the promontory it occupies.
During the Irmandiño peasant revolts, the castle was partially dismantled by local insurgents.
The site contains visible evidence of architectural transition from Roman foundations to medieval military fortifications.
Castillo de Cornatel is a medieval fortress situated on a rocky outcrop overlooking the Sil River valley in the Bierzo region of León. Originally known as the Castle of Ulver, it served as a strategic fortification for the Order of the Temple during the Middle Ages. The site preserves significant remnants of its defensive walls, a keep, and vaulted interior chambers. Archaeological excavations have revealed layers of occupation dating back to the Roman period when the area was exploited for gold mining. It functioned as an administrative center for the Knights Templar before transitioning to the jurisdiction of the Counts of Lemos. The fortress played a critical role in the 15th-century Irmandiño Revolts, during which it suffered significant structural damage. Extensive restoration efforts in the 21st century stabilized the masonry to allow for public access. The site provides an unobstructed vantage point over the Médulas landscape and the surrounding valley floor.
