The cathedral, dedicated to Saint Cetteus, patron saint of Pescara, has been the seat of the Archbishop of Pescara-Penne since the creation of the archdiocese in 1982. The present Romanesque Revival building, originally called the "Tempio della Conciliazione" ("Temple of Conciliation"), was constructed in the 1930s, replacing the medieval church of San Cetteo.
