Opera, Milan's southern fringe and the farmland park

Opera borders the southern outskirts of Milan and grew mainly after the Second World War, with residential districts and business areas, while all around it the fields, irrigation ditches and farmsteads of the Parco Agricolo Sud Milano, a protected farmland park, remain. Its territory also includes the Milano-Opera prison, one of the largest in Italy. Noverasco is among its hamlets.

There is no train or metro: getting to Milan means going by road. Public transport timetables show 17 stops served by 4 bus routes, which run towards the metro lines in the city's southern districts. If you work in central Milan, work out the journey from the exact address, because the walk to a stop varies a lot from street to street.

The population has grown in recent years: 14,340 residents in 2023 according to Istat, the national statistics office, up 8.4% on 2011. The town is older than the Metropolitan City as a whole, with an estimated average age of 47.0 against 45.6 and over-65s at 26.5% against 23.0%. Foreign residents are 8.0%. Incomes are high but below the metropolitan average, which Milan itself pushes up. Schools and supermarkets in Overture Maps data are above average per resident.

Opera is in seismic zone 3 of the Civil Protection scale, like 59 other municipalities around Milan, while 73 are in zone 4; expected ground acceleration is low, about 0.054 g. In a block of flats from the 1960s or 1970s, the state of the facades and roof, any approved extraordinary works and the energy rating matter more, given the cold, foggy winters (climate zone E).

On the water-rich plain south of Milan the report checks flood-prone areas for the address, and the Revenue Agency's cadastral maps let it trace the building's land parcel.

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