The creation of the diocese of Orihuela Historical milestone · Orihuela, El Baix Segura, Alicante Image of Orihuela, not of the place itself. In 1564 Orihuela obtained a diocese of its own, separated from that of Cartagena, after a long suit by the city to stop depending ecclesiastically on Murcia. The former church of El Salvador then became the cathedral of the new see. 1564 Photo: Keith Williamson from Bigastro, Spain (CC BY 2.0) What to see and do in Orihuela
