Colleferro, the factory town in the Sacco valley
Colleferro is a young town by Lazio standards. It grew in the early twentieth century around the Bombrini Parodi Delfino explosives factory in the Sacco valley, and only later became a municipality in its own right. Industry is still here, now mainly aerospace: Avio, the company that builds the Vega rockets, has its headquarters in the town.
The location suits Rome commuters: the Colleferro junction on the A1 motorway and the station on the Rome to Cassino line put the capital less than an hour away. Buyers will find a planned town, with workers' housing, post-war blocks and newer districts towards the valley. One thing to know: the Sacco valley around Colleferro is a national contaminated site awaiting clean-up, because of pollution left by industrial processing. For farmland, vegetable plots and wells, check the restrictions in force with the council and ARPA, the regional environmental agency.
Istat, the national statistics office, counts 20,454 residents in 2023, down 5.2% since 2011. Over-65s make up 25.4%, more than the average for the province of Rome (22.9%), and foreign nationals 9.8%. Services are plentiful for a town of this size: 24 schools, 24 healthcare sites including the hospital and 32 sports facilities, all above the provincial rate per resident. Average incomes are below the provincial figure, which Rome pushes up.
Colleferro is in seismic zone 2 of the Civil Protection classification, like 96 other municipalities in the province, with expected ground acceleration of about 0.150 g. Many buildings date from the 1950s and 1960s, so before buying ask for the structural design, the inspection certificate and the extraordinary works the building has carried out.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report checks landslides and flooding along the Sacco and the valley ditches for the address.

For anyone buying in Colleferro, 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.
