Palermo is the main Sicilian industrial and commercial center: the main industrial sectors include tourism, services, commerce and agriculture. Palermo currently has an international airport, and a significant underground economy. In fact, for cultural, artistic and economic reasons, Palermo was one of the largest cities in the Mediterranean and in Europe and is now among the top tourist destinations in both Italy and Europe.
It is the main seat of the UNESCO World Heritage Site Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale. The city is also going through careful redevelopment, preparing to become one of the major cities of the Euro-Mediterranean area.
Roman Catholicism is highly important in Palermitan culture. The Patron Saint of Palermo is Santa Rosalia whose Feast Day is celebrated on 15 July. The area attracts significant numbers of tourists each year and is widely known for its colourful fruit, vegetable and fish markets at the heart of Palermo, known as Vucciria, Ballarò and Capo.
