For example: Corso Francia 1, Collegno.

Collegno, the metro, the Certosa and the river Dora

Collegno borders Turin to the west and is one of the few towns in the ring around the city served by the metro: line 1 starts right here, at Fermi station, and crosses Turin via Porta Susa and Porta Nuova. For people working in the city, that is an advantage few neighbouring towns can match, alongside the ring road and a suburban railway station.

The town grew mostly between the 1950s and 1970s on the back of Turin's industry, and many districts are made up of blocks from that period. The historic centre is small and lies near the Dora Riparia river. The Certosa Reale, a former royal charterhouse that housed the psychiatric hospital for many decades, now holds offices, schools and a large park. Some areas have their own character, such as the Villaggio Leumann, built by a textile industrialist for his workers, and the outlying districts of Borgata Paradiso and Savonera.

The population is slowly shrinking: 48,031 residents in 2023 according to Istat, the national statistics office, 2.1% fewer than in 2011. The average age is 47.8 and over-65s make up 27.1%; households are small, 2.12 people on average, and foreign residents account for 5.8%.

Winters are cold (climate zone E), so for a 1960s or 1970s flat the things that matter most are insulation, windows, heating and service charges. Seismic hazard is low: Collegno is in zone 3 on the Civil Protection Department's scale, like 270 other municipalities in the province, with an expected acceleration of about 0.065 g.

Homes near the Dora should be checked against the flood maps, which the report reads for each address. The Revenue Agency publishes the land registry maps.

  • 48,031 residents; over-65s at 27.1%.

Overview

Collegno is a municipality in the province of Torino, in Piemonte. At the end of 2023 it had 48,031 residents, the third most populous in the province.

Earthquakes

For Italy's Civil Protection Department, Collegno is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (271 of 312) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.065 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the resident population has fallen by 2.1%. The estimated average age is 48 years, in line with the province. 27% of residents are over 65 (the regional figure is 27%). Foreign residents make up 5.8% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Collegno declared an average taxable income of 27,045 euros, in line with the province (27,231 euros). The Italian average is 24,895 euros.

Collegno is in climate zone E, with 2,646 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 302 metres above sea level.

Radon and contaminated sites

Collegno is not among the radon priority areas designated by the Regione Piemonte in 2023. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Collegno: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
