The cathedral of Santa Maria Assunta stands at the top of the main piazza and has been Ravello's religious centre since its founding in 1086. The facade was reconstructed in the 18th century but the interior preserves medieval work of real quality: two pulpits from the 12th and 13th centuries, both supported by marble columns resting on sculpted lions, and a mosaic-encrusted ambo that is particularly fine. The crypt below the high altar holds the relics of San Pantaleone, the town's patron saint.
The museum attached to the cathedral displays the church treasury, including vestments, silver, and archaeological finds from around the town. It is small but well presented. The whole visit — cathedral, museum, and a few minutes in the piazza — takes about an hour.
