Castillo de Camarillas is a 14th-century fortress built around 1369 during the War of the Two Peters, occupying a dominant hilltop position overlooking the town of Camarillas in Teruel province, Aragon. The castle features three semicircular towers reinforced with small stone walls, crowned by a circular masonry tower approximately seven metres in diameter. Designated as a Cultural Interest Asset, the castle served as a refuge for the local population until the 16th century and was reused during the Carlist Wars, remaining as an important testimony to medieval military architecture and the region's turbulent history.
