Terni, the steel city
Terni grew up around industry. From the late nineteenth century its steelworks, and the power stations fed by the rivers Nera and Velino, made it Umbria's industrial hub, and it is still known as the steel city. The Marmore Falls lie within the municipality, and the patron saint is St Valentine, an early bishop of Terni.
The city carries enormous weight in its province: with 106,436 residents at the end of 2023 it holds 49.3% of the population, almost one person in two. Since the 2011 census the population has fallen by 2.5%. The estimated average age is 48.4, slightly lower than the provincial 48.9, and over-65s make up 27.8%. Foreign residents account for 12.2%.
One point not to overlook: Terni is in seismic zone 2, whereas the most common class in its province is zone 3 (17 of 33 municipalities). Another 12 municipalities share the city's zone 2, and 4 are in zone 1. The expected ground acceleration in the built-up area is about 0.17 g, a medium-high value. Anyone buying in an apartment block from the years of industrial expansion would do well to ask for the structural design and details of any upgrading.
On services, Overture Maps data show 102 healthcare facilities (0.96 per 1,000 residents against 0.63 in the province) and 63 supermarkets, less dense than the provincial average (0.59 against 0.74). The Ministry of Health lists 33 pharmacies, 0.31 per 1,000 residents against 0.40.
Cadastral maps are published by the Revenue Agency (Agenzia delle Entrate), and the report uses them to locate the building's plot. Between the basin the city sits in, the course of the Nera and the surrounding hills, landslide and flood hazard and local prices are checked address by address.
