Terralba
Terralba lies on the Campidano plain south of Oristano in western Sardinia. It was the seat of a bishopric documented from the twelfth century, and its cathedral of Saint Peter was built in 1144 under Bishop Mariano. In 1503 the diocese was united with that of Usellus and its seat transferred to Ales. The old Romanesque cathedral was rebuilt beginning in 1821, preserving the site's long ecclesiastical association.
