Santiago Cathedral (Spanish: Catedral de Santiago; Basque: Donejakue Katedrala) is a Catholic Cathedral in the city of Bilbao. The temple was originally built during the 14th-15th centuries as Bilbao\'s main parish church, and was only declared cathedral in 1950 when the Roman Catholic Diocese of Bilbao was officially created. Its origins probably date to well before the foundation of the city in 1300, when Bilbao was little more than a small enclave of fishermen.圣地亚哥大教堂
