Tricesimo, on the Pontebbana road where the hills begin

The name comes from Latin and recalls the thirtieth mile of the Roman road that ran from Aquileia up towards the Alps. Tricesimo still lives along the same route: the Pontebbana main road runs through it, linking Udine, about ten kilometres south, with Gemona, the Canal del Ferro valley and Austria. The town sits where the Friulian plain gives way to the first glacial hills, at around two hundred metres, with its castle on a hilltop facing the city.

It is a residential town in Udine's commuter belt, in the Friuli Venezia Giulia region, with declared incomes above the provincial average. The market offers detached houses with gardens, terraced villas and some restored farmhouses in the hill hamlets, where lanes narrow and the views open onto the Pre-Alps. Commuting to Udine by car is quick, but rush-hour traffic on the Pontebbana needs to be factored in. The area is in climate zone E, with cold, wet winters.

At the end of 2023 there were 7,554 residents, almost the same as in 2011 (down 0.7%), according to Istat, the national statistics office. The average age is 48.2, in line with 48.5 for the province, and over-65s make up 27.5%. Foreign residents are 6.6% and households average 2.14 people.

Earthquakes are the main issue. The Friulian hills were hit hard in 1976, and many houses in the area were rebuilt or strengthened in the years that followed. Tricesimo is in seismic zone 2 on the scale of the Civil Protection Department (Protezione Civile), with expected ground acceleration in the built-up area of about 0.240 g, a high value; further north, towards Gemona and the mountains, 19 municipalities in the province are in zone 1. For a property built before the reconstruction, or altered several times since, ask for the design drawings and the structural sign-off.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps. The report uses them to find the plot and checks slope and landslide hazard in the hills, as well as flood hazard near streams and canals.
