Solza, the Isola Bergamasca and the Colleoni castle

Solza is in the Isola Bergamasca, the strip of land enclosed by the rivers Adda and Brembo west of Bergamo. The village is known for its castle, where tradition says the condottiere Bartolomeo Colleoni was born. The surrounding landscape is dry plain rising towards the first hills, and it is heavily built up: land take is far above that of an average municipality, between houses, roads and industrial areas.

For people working around Bergamo, Lecco and Brianza the location is convenient by car, while the data record no public transport lines inside the municipality. The market consists of detached and terraced houses and small blocks of flats, with few old houses in the core around the castle. Buyers here are mostly looking for a family home with some garden, at lower prices than in the bigger towns.

Istat, the national statistics institute, recorded 1,975 residents in 2023, practically unchanged from 1,961 in 2011 (+0.7%). The average age is 44.1, below 45.2 for the province, and foreign residents make up 8.9%. Incomes are in line with the provincial average.

The municipality is in seismic zone 3 of the Civil Protection classification, with an expected acceleration of 0.081 g. This is a moderate level, but for houses built before recent seismic codes it is still worth asking for the structural paperwork and checking the roof.

For each address the report shows what lies around it, the official landslide and flood maps, and the Revenue Agency cadastral maps, which are published.
