For example: Via Antica Regina 1, Dongo.

Dongo, the upper lake on the western shore

On the western shore of Lake Como, in the upper lake area known as Alto Lario, Dongo is one of the three historic centres of the Tre Pievi, together with Gravedona and Sorico. It has a lakefront, a small harbour and houses that climb towards the mountains behind. Its name is tied to the last days of the Second World War, when the convoy carrying the fleeing Mussolini was stopped here.

For buyers, Dongo is a lake town far from the cities: Como is reached along the Regina road, which is slow in summer, and the Valtellina and Switzerland are closer than Milan. On the market you find flats in small blocks, stone village houses and second homes with views, many used only in summer. Between the streams coming down from the mountains and the low ground by the lake, the report checks the official landslide and flood maps for the address.

Istat, the national statistics office, counted 3,168 residents in 2023, down 9.2% since 2011. The population is among the oldest in the area: an average age of 48.7 against 46.3 for the province, and over-65s at 29.0%. Average incomes are below the Como average, a figure to read knowing that many people work across the Swiss border.

Seismic risk is the lowest possible: zone 4 in the Civil Protection classification, expected ground acceleration 0.041 g. In an old house near the lake, the state of the roof, walls and heating and electrics matters more, as does damp. Winters are cold (climate zone E), though the lake makes them milder than in the nearby valleys.

Key points

  • Upper western shore of the lake, one of the Tre Pievi.
  • 3,168 residents, down 9.2% since 2011.

Overview

Dongo is a municipality in the province of Como, in Lombardia. At the end of 2023 it had 3,168 residents, ranked 58 of 147 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Dongo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 147 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.041 g, a low value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

The estimated average age is 49 years, higher than the province average (46). 29% of residents are over 65 (the regional figure is 24%). Foreign residents make up 4.6% of the population.
