Since the Middle Ages, the Galician Catholic Church has been organized into five ecclesiastical dioceses (Lugo, Ourense, Santiago de Compostela, Mondoñedo-Ferrol and Tui-Vigo). While these may have coincided with contemporary 15th-century civil provinces, they no longer have the same boundaries as the modern civil provincial divisions. The church is led by one archbishop and four bishops. Moreover, of five dioceses, Galicia is divided between 163 districts and 3,792 parishes, a few of which are governed by administrators, the remainder by parish priests.
