Costa Serina, mountain hamlets in the Val Serina

The Val Serina is a side valley of the Val Brembana, and Costa Serina spreads across its slope as a cluster of small hamlets and scattered houses among meadows and woods rather than a single village. The name says a lot: the houses stand on the costa, the mountainside, with sloping roads and open views over the valley. Bergamo is reached by heading down to the Val Brembana and its main road.

It is a place to weigh up carefully. Buyers should think about travel times to work, winter snow and the fact that many houses are old stone buildings, some used only in summer. On a slope, check retaining walls, drainage and car access.

There are 894 residents (2023), down 8.1% on 2011 according to Istat, the national statistics institute. The population is much older than the provincial average: the estimated average age is 50.7 against 45.2, and over-65s are 33.8% against 22.5% in the province. Foreign residents are 2.7% and households average 2.08 people. Declared incomes are lower than the provincial average.

All 243 municipalities in the province of Bergamo are in seismic zone 3 of the Civil Protection classification; in Costa Serina the expected ground acceleration is about 0.092 g. In a stone house needing renovation, the roof and the timber floors are the first things to show an engineer.

Landslide and rockfall hazard changes from hamlet to hamlet: the report reads it from the official maps for the exact address. The Revenue Agency publishes the cadastral maps, so the land parcel can be traced from the address.
