Ardenno, lower Valtellina at the gateway to Val Masino

Ardenno lies on the floor of the lower Valtellina, near the Adda, where the Val Masino opens up. That side valley climbs towards Bagni di Masino and the granite peaks popular with climbers. The village is crossed by the main Valtellina road and has the Ardenno-Masino station on the railway to Sondrio and Tirano in one direction and to Colico and Milan in the other.

Buyers will find a centre of stone houses, a belt of newer detached houses and small blocks, and small clusters on the hillside among terraces and woods. The railway is a real advantage if you work in Sondrio or Morbegno. On the valley floor near the Adda, check the flood maps; on the slopes, the gradient. The report reads both for the individual address.

Istat, the national statistics office, records 3,217 residents (2023), down 1.6% since 2011, a small change. The average age is 47.1, the same as Sondrio province (46.8), and 26.9% are over 65. Foreign residents make up 5.1%. Declared incomes are slightly below the provincial average, and climate zone E means cold winters with little sun in the shortest months.

Ardenno is in seismic zone 3, along with 63 other municipalities in the province, but the expected ground acceleration in the built-up area is low, about 0.059 g. In stone houses the usual checks apply to roof, damp and services, and for 1970s buildings, the energy rating.

Liveability area by area
