Castle of Corbera Monument · Corbera, La Ribera Baixa, Valencia Corbera Castle, whose name means nest of crows, is an 11th-century Muslim fortress built on Roman remains on a promontory overlooking the Ribera Baja and the coast. First mentioned in 1229, it was part of a defensive network together with the castles of Alzira and Cullera, and remained in Muslim hands until its conquest by James I in 1248. In June 1521, during the Guerra de las Germanías, it was besieged and occupied by agermanats from Alzira, who abandoned it at the end of the month as royalist troops approached, leaving it badly damaged; in 1640 Philip IV authorised local residents to use its materials for a street in the town. It retains its entrance, with an arch and barrel vault, and the sixteen-metre albarrana tower. Photo: Juandetorres (CC BY-SA 3.0 es) What to see and do in Corbera
