is the largest island in the Mediterranean Sea, strategically located centrally between Gibraltar and the Suez canal. The island is mainly mountainous and hilly, with high coasts on the Tyrrhenian side, lower and at times marshy on the Sicilian canal; mixed on the Ionian Sea. The highest reliefs arise in the northeastern sector: here are the massive volcanic apparatus of Etna, the highest in Europe. In addition to Etna, Stromboli and Vulcano in the Aeolian Islands are also active volcanoes. Along the coast of the southeastern end of the island, there are some lakes and coastal ponds.
Of particular note is the city of Messina which houses an important biosphere reserve as well as cultural heritage, the Aeolian Islands, a UNESCO World Heritage Site since 2000. The territory is among the richest on the island and two of the most important tourist resorts of Sicily are part of it: Taormina and the Aeolian Islands (Alicudi, Filicudi, Lipari, Panarea, Salina, Stromboli, Vulcano).
Sicily extends between provinces, metropolitan cities and 390 municipalities. Among the most important are Palermo, Agrigento, Enna, Caltanissetta, Catania, Messina, Ragusa, Syracuse, Trapani, Castellammare del Golfo, Favignana, Pantelleria, Marsala and San Vito Lo Capo.
