Termoli's cathedral crowns the small walled promontory of the old town, and it looks across the Adriatic in the manner of the great Apulian churches. Its Romanesque façade, twelfth to thirteenth century, is a smooth wall of pale stone with a single rose window above a tight row of arcades on slim columns, the same vocabulary as the basilica of San Nicola in Bari.
Below the church a crypt keeps fragments of the older façade, a Romanesque mosaic floor with animals, and the relics of San Basso, found in 1760, and of San Timoteo, Saint Paul's companion, discovered in the 1940s. Damaged by an earthquake in 1456 and by a raid in 1566, it was stripped of Baroque additions in the twentieth century.
