Castillo de Dos Aguas, located in the Hoya de Buñol region of Valencia, is a 12th-century fortress named after one of its medieval lords, Antonio Vilaragut. Today only the distinctive square tower remains—measuring 19 by 19 meters—built from rammed earth masonry and known locally as the Tower of Vilaragut. This structure represents an important piece of regional medieval heritage, having passed through various lordships including the Roig de Corella family. The castle's placement in the center of the town of Dos Aguas reflects its historical role as both a defensive structure and administrative center during the medieval period.
