Alcañiz

Alcañiz stands beside the Guadalope beneath the castle of the Order of Calatrava. Granted the town and fortress in 1179, the military order made the castle a convent and the seat of its chief commandery in Aragon. In 1412, during the crisis following King Martin’s death without an heir, representatives of Aragon and Catalonia agreed at Alcañiz on a procedure for choosing his successor. Their agreement led to the Compromise of Caspe.
