Biassono, Brianza on the edge of Monza Park

Biassono borders Monza Park to the south, one of the largest walled parks in Europe, and part of its land actually lies inside the park walls. This is the heart of Brianza, north of Monza and about twenty kilometres from Milan, an area where towns run into each other and houses, villas and small businesses cover more than half the land.

For Milan there is the train: Biassono-Lesmo Parco station is on the Monza to Molteno and Lecco line, and in the operators' open timetables (GTFS format) the town is served by 2 lines in total, rail and bus. By car the Valassina expressway, towards Lecco and Milan, is a few minutes away. The historic centre is small, and most homes are in residential districts built from the 1960s to the present.

Biassono is growing. Istat, the national statistics office, counted 12,336 residents in 2023, up 5.5% on 2011. It is slightly older than the province of Monza and Brianza (average age 47.0 against 45.9) and has a modest share of foreign nationals, 6.4%. Declared incomes are above the provincial average, itself among the highest in Lombardy.

Earthquakes are not much of a worry here. Biassono is in seismic zone 3 of the Civil Protection classification, like 39 other towns in Brianza, but the expected ground acceleration is low, about 0.055 g. Buyers of a house or flat tend to focus on the energy rating, service charges and the condition of the heating and wiring, as well as distance from busy through roads.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps and the report finds the land parcel from the address. The Lambro, which runs through the park, is the nearest river: for homes on lower ground the report checks the official flood maps at the exact spot. With the park so close, the distance to green space is also measured from the address.
