Geography

The province of Trapani borders the Tyrrhenian Sea to the north, the Mediterranean Sea to the south, and the Strait of Sicily to the west. It is bordered to the east with only the provinces of Palermo and Agrigento. The territory has few flat areas, although with the exception of the mountains of Sparagio (1,110 m) and Inici (1,065 m), most land is under 1,000 metres. The northwestern part is rugged in comparison to the south. The province also includes the archipelago of the Aegadian Islands belonging to the comune (municipality) of Favignana, the island of Pantelleria which is the largest of Sicily, in the comune of the same name, and the Stagnone Islands, which belong to the comune of Marsala. The Egadi Islands consist of three main islands, Favignana, Levanzo and Marettimo and two islets, Formica and Maraone.

The province of Trapani has a number of rivers, but most are not of notable size or importance, except for the Belice on the border of the province, and the Birgi, with a length of about 40 km. Other rivers include the torrential Modione, Mazaro, the Fiume, the Salemi and the Sossius, the latter of which flows into the Mediterranean Sea at the resort of Berbaro.

Natural lakes include the Gorghi Tondi and Preola, in the comune of Mazara del Vallo, and the Lago di Venere in Pantelleria. There are also three man-made lakes, Lago Rubino, created by a dam across the Cuddia River, which is part of the catchment area of the Birgi, at Lago Trinità in Castelvetrano, and the lake of the same name at the resort of Paceco. However, there is also a coastal lagoon, the Stagnone Lagoon, within a 2000-hectare reserve on the stretch of coast between Punta Alga and Cape San Teodoro, near Marsala, in an area which was once an important naval base and commercial for the Phoenicians. The waters are shallow and very salty, with marshland. The lagoon consists of four islands: Isola Longa Santa Maria, San Pantaleo and Schola. and the Aegadian Islands are also administratively a part of Trapani province.

Economy

The Province of Trapani is a major centre for viticulture in the Val di Mazara wine region.

The province is also historically associated with marble quarrying and ornamental stone production, particularly around Custonaci, Trapani, Erice and San Vito Lo Capo. The Custonaci marble basin is among the largest in Italy and has been described as one of the largest in Europe.

In the early 19th century, Giuseppe Maria Di Ferro described several prized local stone varieties, including "Libeccio", "Capriccioso", and "Pietra Incarnata", noting their use in churches and monumental architecture in Naples and Rome. He also described quarrying activity around Custonaci and the slopes of Monte Erice.
