Cologno al Serio, a moated village on the Bergamo plain

On the plain south of Bergamo, a few kilometres from the river that gives it its name, Cologno al Serio keeps something rare in Lombardy: the moat that still runs round the old village, along with stretches of its walls. The centre is compact, made up of traditional courtyard houses; around it, districts of detached houses and blocks of flats have grown up, with industrial areas on the edges.

Bergamo is about fifteen kilometres away, and Orio al Serio airport and the A4 motorway are a short drive. People here live and work on the plain, between local firms, Bergamo and neighbouring towns such as Urgnano and Spirano. If you are buying in the centre, courtyard houses are often split among several owners and need work: be clear about shared areas, rights of way and the state of the roofs.

The population is growing and young. In 2023 there were 11,105 residents, up 4.8% since 2011 according to Istat, the national statistics office; the average age is 44.1 against 45.2 for the province of Bergamo, and over-65s make up 21.2%. Foreign residents account for 11.3%, and households average 2.44 people. Average incomes are a little below the provincial figure.

All 243 municipalities in the province of Bergamo are in seismic zone 3 on the Civil Protection Department's scale, an intermediate hazard. In Cologno the expected ground acceleration in the built-up area is about 0.123 g. For masonry courtyard houses, often altered several times, checking the structure and floors before starting work avoids surprises.

Among mapped services, schools are few for the population, 4 in all, or 0.36 per 1,000 residents against 0.87 in the province. Near the Serio and along irrigation ditches and canals, flood hazard varies from spot to spot, and the report checks it at the address with the official maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps.
