Whenever I see the church of San Cataldo, I feel Palermo is welcoming me home. The red domes of this ancient church overlook Via Maqueda and Piazza Bellini. San Cataldo was built during the early-Norman era in the 1150s by Maio of Bari, William I’s top emir, or commander. Its cherry-on-top domes and elegant window details illustrate the unique Arab-Norman, UNESCO recognized architectural style found only in Sicily.
