Coggiola, the Valsessera and Biella's wool tradition

Coggiola is a village in the Valsessera, the valley of the Sessera stream in the eastern part of the Biella area. This is wool country: the woollen mills shaped the valley, with factories along the stream and workers' housing close to them. Biella and Borgosesia are reachable by car.

For buyers, the valley offers houses that are often large and need a little more care. Many buildings are decades old, so check the heating and electrics, insulation and roof, and climate zone E means long winters. Hamlets on the slopes are sunnier and quieter, those near the valley floor handier for services. A winter viewing helps you see how much sun the house really gets.

Istat, the national statistics office, counts 1,632 residents in 2023, down 18.2% from 1,996 in 2011. The population is older: average age 53.2 against 49.7 for the province, with over-65s at 35.2%. Households are small, averaging 1.91 people.

Earthquake risk is low. Coggiola is in seismic zone 4, like 50 of the 74 municipalities in the province, with an expected ground acceleration of 0.044 g. In older houses, upkeep and the condition of the walls matter more.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report works back from the address to the land parcel. In a narrow valley, landslides and stream floods depend on the precise spot, and the report reads the official maps for the address.

Key points

Overview

Coggiola is a municipality in the province of Biella, in Piemonte. At the end of 2023 it had 1,632 residents, ranked 25 of 74 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Coggiola is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (50 of 74) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.044 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 53 years, higher than the province average (50). 35% of residents are over 65 (the regional figure is 27%). Foreign residents make up 5.8% of the population.
