The union of the dioceses of Segorbe and Albarracín Historical milestone · Segorbe, El Alto Palancia, Castellón Image of Segorbe, not of the place itself. A papal decision that in 1259 united the episcopal sees of Segorbe and Albarracín: after Segorbe was conquered by the Aragonese Christians, Pope Innocent IV entrusted the ecclesiastical jurisdiction of the area to the bishop of Albarracín in 1247, and on 18 March 1259 Alexander IV formally decreed the union of the two churches. The resulting bishopric straddled the crowns of Aragon and Castile, with Segorbe in the Kingdom of Valencia and Albarracín in Aragon, a singular situation that was maintained until Gregory XIII separated the two dioceses again in 1577, precisely because of that difference in kingdom. This union explains the ecclesiastical weight that Segorbe kept for centuries, today the seat, together with Castellón, of the diocese of Segorbe-Castellón. 1259 Photo: Enrique Íñiguez Rodríguez (Qoan) (CC BY-SA 3.0) What to see and do in Segorbe
