Mossa, between the Collio hills and the Gorizia plain

Mossa is a village in the Gorizia area, a few minutes from Gorizia itself, where the first vine-covered hills of the Collio give way to the plain stretching towards the Isonzo river. The centre is compact and surrounded by vineyards and fields; Gorizia is the reference for work, schools and the hospital, while Udine and Trieste are within driving distance.

Buyers here should know about one particular feature: the Gorizia area uses the tavolare land register system, inherited from Austrian rule. Ownership passes when it is entered in the land book (libro fondiario), kept by the land registry office, rather than through the simple registration used elsewhere in Italy. The notary handles this, but it helps to know so you understand the timing and paperwork. The Revenue Agency (Agenzia delle Entrate) cadastral maps, on the other hand, are published, and the report still traces the address to its land parcel.

Istat, the national statistics office, counted 1,516 residents in 2023, down 8.6% since 2011. The average age is 49.2 against 48.0 for the province, and over-65s make up 28.6%. Foreign residents account for 2.7%. Declared incomes are above the provincial average.

In the province of Gorizia 10 municipalities are in seismic zone 2 and 15 in zone 3. Mossa is in zone 2, with an expected ground acceleration of about 0.193 g. For a building put up before the seismic codes, ask for the design and any later structural work.

Between hills and plain, landslide and flood hazard change from one address to the next, and the report reads them for the exact spot.

For anyone buying in Mossa, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

Official databases list no contaminated sites in Mossa.

Landslides and flooding

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

Mossa uses the tavolare (land book) system, but the Revenue Agency still publishes the maps: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.
