Gela, a Greek city on the gulf and an energy hub
Gela is one of the oldest cities in Sicily, founded by Greek settlers on the south coast, and the walls at Capo Soprano and the acropolis survive from that past. In the twentieth century its story took a different turn with a large petrochemical plant, now converted into a biorefinery. It brought jobs, and the industrial area became a site of national interest for environmental clean-up.
It is the most populous municipality in the province of Caltanissetta, larger than Caltanissetta itself, with 28.7% of the province's residents. The town stretches along the gulf, with a seafront and beaches, and behind it opens the plain, farmed for artichokes, vegetables and wheat. The Allied landings of 1943 took place on this very coast.
Many districts grew quickly during the industrial boom, often outside any plan, and unauthorised building was a well-known problem in Gela for decades. Before buying, have a surveyor check the planning permits, any amnesty paperwork (condono) and the occupancy certificate, and look at how far the property is from the industrial zone.
Istat, the national statistics office, counted 70,856 residents in 2023, down 6.4% on 2011, or 4,812 fewer people. The town remains younger than the province, with an average age of 43.7 against 45.2, and foreign residents are few, at 2.1%. Average declared incomes are above the provincial figure.
Gela is one of only 4 municipalities in the province in seismic zone 2, while the other 18 are in the lower zone 3; expected ground acceleration is about 0.091 g. In apartment blocks built between the 1960s and 1980s, ask whether any structural surveys exist. The climate is hot (climate zone B), so in summer keeping the sun out matters more than heating.

For anyone buying in Gela, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

The estimated average age is 44 years, lower than the province average (45). 21% of residents are over 65 (the regional figure is 23%). Foreign residents make up 2.1% of the population.
