Arbitral award of Torrellas Historical milestone · Torrellas, Tarazona y el Moncayo, Zaragoza Image of Torrellas, not of the place itself. The Arbitral Award of Torrellas, signed on 8 August 1304 in this municipality of Zaragoza situated on Mount Moncayo, between the Castilian city of Ágreda and the Aragonese city of Tarazona, ended the dispute over the borders of the kingdom of Murcia between the crowns of Castile and Aragon, as well as resolving the claims to the Castilian-Leonese throne of Alfonso de la Cerda, grandson of Alfonso X the Wise. For this reason it is also known as the Concord of Ágreda or the Treaty of Tarazona. Its clauses, approved by Ferdinand IV of Castile, James II of Aragon, Denis I of Portugal and Muhammad III of Granada, left the Segura as the border: Aragon retained Alicante, Elche, Orihuela and Cartagena, while Castile kept Murcia and Lorca. 1304 Photo: Ecelan (CC BY-SA 3.0) What to see and do in Torrellas
