Oltrona di San Mamette, hills between Como and Varese
Oltrona di San Mamette is a residential village in the hills of the Como area, on the strip of land that runs from the provincial capital towards the province of Varese. Homes sit on low glacial ridges, between patches of woodland and small clusters that have filled up with detached houses and low blocks over recent decades. Most residents work elsewhere, in Como, Varese or further afield in Lombardy, and they get around by car.
There is no railway station in the village and no line listed in the public timetables. If you commute, what matters is the distance to the main roads and to the most convenient station in a nearby town, which the report measures from the address. Everyday services in the village are few, as you would expect for a place this size, and for many things people drive to the larger towns nearby.
According to Istat, the national statistics office, there are 2,355 residents (2023), up 2.9% on the 2,289 of 2011. The average age is 45.4, slightly below the provincial figure of 46.3, and 22.3% of residents are over 65. Foreign residents make up 5.2%. Incomes are in line with the rest of the province.
Earthquake risk is low. All 147 municipalities in the province are in seismic zone 4, the lowest class set by the Civil Protection department, and the expected ground acceleration is about 0.039 g. In a house from the 1970s or 1980s, insulation, the boiler and the roof matter more, not least because winters here are long and cold.
The Revenue Agency's cadastral maps cover the municipality, so the report can trace the land parcel and building from the address.
