Caldes, its castle and the floor of the Val di Sole
Caldes lies at the entrance to the Val di Sole in western Trentino, on the floor of the Noce valley and the slopes around it, at about 700 metres. The village is known for Castel Caldes, the medieval castle with its tower, easy to spot from the village. Further up is Malè, the main town of the valley, and beyond that the ski slopes and the Tonale pass.
It is a small municipality but not a shrinking one: there were 1,112 residents in 2023, up 2.0% on 2011. The average age is 45.9, close to the provincial figure of 45.4, over-65s are 24.5% and foreign nationals 5.5%. Declared incomes are below the provincial average.
Buyers here find village houses, many renovated in recent decades, and newer homes on the slopes. What matters is sun exposure, winter access and insulation: the climate zone is F, the coldest, and heating is a major item in the household budget.
Earthquake risk is low. Caldes is in seismic zone 4, like 14 other municipalities in Trentino, with an expected ground acceleration of 0.049 g. In the mountains, snow, roofs and the upkeep of retaining walls matter more than tremors.
There is one important difference from most of Italy. In Trentino, property is recorded in the land book (libro fondiario, the "tavolare" system), and the Revenue Agency (Agenzia delle Entrate) does not publish parcel maps: the report flags this in the land registry section, and plot details must be checked with the land book office and the Province's own cadastre. Landslides and flooding along the Noce and on the slopes are still checked for the address on the official maps.

Overview
Caldes is a municipality in the province of Trento, in Trentino-Alto Adige/Südtirol. At the end of 2023 it had 1,112 residents, ranked 104 of 166 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Caldes is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 15 of 166 municipalities in the province are in zone 4.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.049 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.
Population
Compared with the 2011 census, the resident population has grown by 2.0%. The estimated average age is 46 years, in line with the province. 24% of residents are over 65 (the regional figure is 22%). Foreign residents make up 5.5% of the population. On average, a household has 2.3 members.

Radon and contaminated sites
Caldes is not among the radon priority areas designated by the Provincia autonoma di Trento in 2026. According to the ISPRA map, the estimated radon emission in the municipality is medium. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list no contaminated sites in Caldes.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Caldes: the report checks the address against the ISPRA maps.
House prices
The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
Land registry
For Caldes the Revenue Agency does not publish cadastral maps: the land registry here uses the tavolare (land book) system. The report cannot give a parcel reference, but it still checks risks, services and transport at the address and states this clearly.
Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 26 inhabited census areas in Caldes. Half of the residents live in areas scoring 52 or more.
