For example: Via Guglielmo Marconi 1, Denno.

Denno, among the orchards of lower Val di Non

In lower Val di Non the landscape is almost entirely apple orchards: dense rows of trees, hail nets, farm tracks between one orchard and the next. Denno is here, on the valley side south of Lake Santa Giustina, in an area where apples are the main source of income. Trento is reached by heading down towards the Adige valley, in about three quarters of an hour.

The population is stable and not especially old. In 2023 there were 1,249 residents, practically the same as in 2011 (1,252), according to Istat, the national statistics office. The average age is 45.9 (45.4 in the province), over-65s are 24.4% and foreign residents 13.4%. Households have 2.32 people on average. Declared incomes are below the average for the province of Trento.

There is one technical point buyers should know. Trentino uses the tavolare land register: ownership, easements and mortgages are recorded in the Libro fondiario (land book), and the Revenue Agency (Agenzia delle Entrate) does not publish maps for these municipalities. The report therefore cannot show the cadastral plot and says so; title checks go through land book searches, which the notary carries out anyway.

Earthquake hazard is low: seismic zone 3 of the Civil Protection classification, like 146 other municipalities in the province, with an expected acceleration of 0.054 g. The climate matters more: zone F, cold winters, so insulation and heating weigh on running costs.

Otherwise the report works on the address as it does elsewhere: it checks the available official landslide and flood maps, measures elevation and slope and works out distances to schools, the pharmacy and shops.

Key points

  • Lower Val di Non, among orchards south of Lake Santa Giustina.
  • Tavolare land register: no Revenue Agency maps.
  • Stable population: 1,249, foreign residents at 13.4%.
  • Seismic zone 3, expected acceleration 0.054 g.

Overview

Denno is a municipality in the province of Trento, in Trentino-Alto Adige/Südtirol. At the end of 2023 it had 1,249 residents, ranked 93 of 166 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Denno is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (147 of 166) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.054 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the number of residents is nearly unchanged. 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 13.4% of the population. On average, a household has 2.3 members.

Income and climate

In tax year 2024, taxpayers in Denno declared an average taxable income of 20,570 euros, below the provincial average (25,718 euros). The Italian average is 24,895 euros.

Denno is in climate zone F, with 3,060 heating degree days, with no limits on when heating may be used. The same table puts the town hall at 429 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Denno has 2 schools and 1 pharmacy. The Overture Maps data also lists 1 grocery shop and 1 healthcare facility.

There are 0.8 pharmacies per 1,000 residents, more than the province average (0.3).

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 4.9% of the land in Denno, compared with 3.1% in the province and 2.9% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Denno 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 Denno.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Denno: 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 Denno 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 8 inhabited census areas in Denno. Half of the residents live in areas scoring 63 or more.
