This museum is dedicated for the most part to the cult of St. Agatha, patron saint of Catania. The museum is joined architecturally to the Duomo, its windows opening onto Piazza Duomo. Most of the artworks consist of vestments, altar furnishings, and relics from the bishops' palace. This minor museum need occupy no more than an hour of your time. The best of the treasure-trove is found in Hall II: Look for a relic arm of St. George as well as St. Cataldo's relic bust, attributable to Paolo Guarna, one of the most famous goldsmiths of Catania in the 16th century.
