Catania is the second largest city in Sicily, after Palermo, and among the ten largest cities in Italy. It is located on Sicily's east coast, at the base of the active volcano, Mount Etna, and it faces the Ionian Sea. In January 2015, there were 315,601 people residing in Catania.

Catania was founded in the 8th century BC by Chalcidian Greeks. The city has weathered multiple geologic catastrophes: it was almost completely destroyed by a catastrophic earthquake in 1169. A major eruption and lava flow from nearby Mount Etna nearly swamped the city in 1669 and it suffered severe devastation from the 1693 Sicily earthquake.

During the 14th century, and into the Renaissance period, Catania was one of Italy's most important cultural, artistic and political centres. It was the site of Sicily's first university, founded in 1434. It has been the native or adopted home of some of Italy's most famous artists and writers.

Catania today is the industrial, logistical, and commercial center of Sicily. Its airport, the Catania-Fontanarossa Airport, is the largest in Southern Italy. However the central "old town" of Catania features exuberant late-baroque architecture, prompted after the 1693 earthquake, and is a UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage Site.

Catania is the first economic and industrial hub of Sicily. The city is famous for its mainly petrochemical industry, and the extraction of sulphur. The sea port of Catania is linked to the road-rail distribution hub of Bologna.
