The lively Kalsa is known for Renaissance art in the 15th-century Palazzo Abatellis and the Byzantine mosaics of the 12th-century church of Santa Maria dell’Ammiraglio. Fontana Pretoria, dating from the 1500s, features life-size marble statues. Dining options run from street food to gourmet fare, while shops selling handmade ceramics, woodwork, and textiles line the alleyways. By night, busy bars serve a young crowd.
