Treviolo, Bergamo's western suburbs

Treviolo borders Bergamo to the west and belongs to the ring of suburbs that has grown up around the city, between Curno, Lallio and Dalmine. Besides the main village it includes hamlets such as Curnasco and Albegno, each with its own church and small centre, now joined together by streets of houses and blocks of flats.

People choose Treviolo to be close to Bergamo without living in the city. The centre is a few kilometres away, the large retail areas on the western edge of Bergamo are close at hand, and average declared incomes are well above the provincial average. On the other hand the land is heavily built up, and busy roads run between the hamlets.

Istat, the national statistics office, counted 10,823 residents in 2023, up 5.1% on 2011. The estimated average age of 45.1 is almost the same as the province (45.2), over-65s are 21.4% and foreign residents 6.5%. Parks and sports facilities are more common than average: 0.37 green spaces per 1,000 residents against 0.19 across the province.

For earthquakes, the whole province is in the same band: all 243 municipalities are in seismic zone 3 of the Civil Protection classification, and the expected acceleration in Treviolo is about 0.107 g. In a block of flats from the 1970s or 1980s, the energy rating, heating costs and works already approved by the owners' meeting weigh more heavily.

The Revenue Agency (Agenzia delle Entrate) publishes Treviolo's cadastral maps, and the report traces each address to its plot. The plain is crossed by irrigation channels, so flood hazard too is read at the exact position of the house, not as an average for the municipality.

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