Mantello, the lower Valtellina valley floor by the Adda

On the flat floor of the lower Valtellina, the long Alpine valley of the province of Sondrio, Mantello lies near the river Adda at just over 200 metres. Around it are meadows, fields and the mountains that close the valley on both sides. For a wider range of services people go to the larger towns of the lower valley, such as Morbegno, while Lake Como and the road towards Lecco and Milan can be reached without big climbs.

It is a small municipality but not an ageing one. Istat, the national statistics office, recorded 753 residents in 2023, up 2.9% on 2011. The average age is 45.3, lower than the 46.8 of the province of Sondrio, and over-65s make up 23.9% against 25.3%. Households have 2.23 members on average and foreign residents account for 9.2%. Average declared income is close to the provincial figure.

The flat valley floor makes getting around and building easy, but it brings the question of water. The river, side streams and groundwater should all be considered before buying: the report checks the address against the official flood maps and, for houses at the foot of the slopes, the landslide and debris-fan maps too. Basements and cellar rooms deserve an extra look.

Mantello is in seismic zone 4, the lowest class, like 12 other municipalities in the province. Expected ground acceleration is about 0.048 g. This is climate zone E: cold winters and valley fog, so good insulation makes a difference to energy use.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps for Mantello and the report links each address to its land parcel.

Key points

  • Flat lower Valtellina valley floor, near the Adda.

Mantello is a municipality in the province of Sondrio, in Lombardia. At the end of 2023 it had 753 residents, ranked 54 of 77 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Mantello is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 13 of 77 municipalities in the province are in zone 4.

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