The castle of Alfajarín and the barony of the Cornel family Monument · Alfajarín, Comarca Central, Zaragoza The castle of Alfajarín crowns one of the hills bordering the Ebro valley, next to the hermitage of the Virgen de la Peña, and formed part of the defensive belt protecting the trade routes of Andalusian Saraqusta; it may have been built in the 10th or 11th century to watch over the crossing of the Ebro. Taken by Alfonso I el Batallador in 1119 and again in 1131, it returned to Muslim hands until its final reconquest in 1141 under Ramón Berenguer IV. The Cornel family governed the place from 1293, by grant of Jaime II de Aragón, and fortified it; in 1437, when the barony died out, it passed through various owners, among them Ramón de Espés and the Alagón family, until it was abandoned and fell into ruin around the 19th century. 1293-1437 Photo: Ecelan (CC BY-SA 3.0) What to see and do in Alfajarín
