Castle of els Alcalans Monument · Montserrat, La Ribera Alta, Valencia The castle dels Alcalans was a medieval fortification located in the municipal district of Montserrat (Valencia), in the comarca of the Ribera Alta, near the river Magre, in the Alcalans valley to which it gives its name. It occupies a southern hill of the Sierra Falaguera, near the Cova Fumà, on the boundary with Llombai. Built of limestone, it had a double wall and two enclosures: an upper one, military and residential, with a courtyard and cistern, and a lower one with a large albacar and a lists yard defended by an outer wall of which remains up to three metres high are still preserved. Its first construction phase dates back to the 11th century, associated with the Taifa of Valencia, and a second, from the 12th and 13th centuries, from the Almohad period.
