Chances are, during your stay in Catania you'll eventually wander beneath the Porta Uzeda, either on the above walking tour or as part of your exploration of the Piazza Duomo, which it fronts. Beneath it are vaulted spaces loaded with the fancifully hand-painted pottery skillfully made in Caltanissetta, a city in central Sicily that has churned out tons of the stuff during the past centuries. Look for gaily decorated serving dishes, candelabras painted like members of the 19th-century bourgeoisie, and all manner of art objects.
