DUOMO SANTA MARIA ASSUNTA E SAN BERARDO

Begun in 1158, then reworked in the ^fourteenth and ^eighteenth centuries, the cathedral has a silver altar front by Nicola da Guardiagrele (a ^{fifteenth-century} goldsmith). At the crossing of the transept, the chapel (^18th century) contains the polyptych of Sant'Agostino, work of the Venetian Jacobello del Fiore.

Roman remains. To the left of the cathedral, from Corso Vincenzo Cerulli, the ruins of a Roman theater of the ^third century AD and an amphitheater of the ^fourth century are visible.
