Castelrotto, the Sciliar plateau and the Alpe di Siusi

Castelrotto, Kastelruth in German, lies on a sunny plateau at the foot of the Sciliar (Schlern) massif, above the Isarco valley, more than a thousand metres up. The municipality is large and includes Siusi, several hamlets and most of the Alpe di Siusi (Seiser Alm), the vast high pasture that becomes a ski area in winter and a hiking area in summer. German is the main language, and the local economy rests on tourism and mountain farming.

Tourism shows in the figures: Overture Maps lists 82 bars and restaurants, 11.68 per 1,000 residents against 6.18 in the province. Public transport means buses, with 208 stops served by 33 routes linking the hamlets with each other and with the valley.

There are 7,019 residents (2023), up 8.7% since 2011, with an average age of 43.1, in line with South Tyrol as a whole, and foreign residents at 9.8%. Declared incomes are above the provincial average.

Buying here follows its own rules. South Tyrol uses the land book system (sistema tavolare): ownership is proved by registration in the land book, and the cadastre is run by the autonomous province of Bolzano, while the national Revenue Agency does not publish its maps. The report therefore cannot reach the cadastral parcel and says so. Many homes are also subject to a residency restriction (convenzionamento), meaning they may only be used by people who live or work in the province. The restriction is recorded in the land book and must be checked before you make an offer, with a local notary or surveyor.

Earthquakes are not a concern: all 116 municipalities in South Tyrol are in seismic zone 4, the lowest class set by the Civil Protection Department, and the expected ground acceleration is about 0.056 g. Insulation and heating matter more, with long winters (climate zone F), and on the slopes so do landslides and debris flows, which the report checks for the address.

Earthquakes

For Italy's Civil Protection Department, Castelrotto is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 116 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.056 g, a moderate 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.

Official databases list one contaminated site, or site still under investigation, in Castelrotto, and 3 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Castelrotto: 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 Castelrotto 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.
