Pescara Cathedral (Italian: Duomo di Pescara, Cattedrale di San Cetteo Vescovo e Martire) is a Roman Catholic cathedral in the Via D'Annunzio in the city of Pescara. 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.
The construction of the present church was linked with the wave of intensive building activity that accompanied the creation of the city and province of Pescara in 1927. The medieval church of St. Cetteus (Italian: Chiesa di San Cetteo) that formerly stood on the site had fallen into such disrepair that it was demolished (a few traces of the old building can be seen on the pavement opposite). The construction of the new church was vigorously promoted by the writer Gabriele D'Annunzio, who had been baptised in the demolished church, and who was a generous donor to the project. D'Annunzio, one of whose principal concerns was to build a suitable tomb for his mother, commissioned the architect Cesare Bazzani. Work lasted from 1933 to 1938 or 1939. The façade had to be reconstructed after World War II as a result of war damages.
The original name of the new building, the Tempio della Conciliazione ("Temple of Conciliation"), is connected to the Lateran Pacts of 1929, marking the agreements made between the Italian Fascist government and the Vatican.
