Pont-Saint-Martin, a Roman bridge at the gateway to the valley
The arched Roman bridge over the Lys torrent, still standing after two thousand years, gives the town its name and is its emblem. Pont-Saint-Martin is the first sizeable town in the Aosta Valley for anyone arriving from the Canavese area of Piedmont: here the Lys, coming down from the Gressoney valley, flows into the Dora Baltea. The town has a station on the railway to Aosta and a junction on the A5 motorway, and serves the lower valley as a centre for shops and services.
For buyers, location is the strong point: Ivrea and the Canavese are close, Aosta and Turin can be reached by train or motorway, and the Gressoney ski slopes lie up the Lys valley. The market includes flats in blocks on the valley floor, older houses in the old quarter around the bridge and homes on the terraced slopes, once planted with vines. Overture Maps data record 5 school sites, 4 supermarkets and 20 bars and restaurants.
The population has dropped: Istat, the national statistics office, counted 3,541 residents in 2023, down 11.6% since 2011, though the town is still among the largest in the region. The average age is 47.4, with over-65s at 27.0% against 25.3% for the region, and foreign residents at 9.7%. Average declared incomes are below the regional average.
All 74 municipalities in the Aosta Valley are in seismic zone 3, as classified by the Civil Protection Department (the national emergency agency). In Pont-Saint-Martin the expected acceleration is low, about 0.050 g. For stone houses in the old quarter, roofs, damp and services are what matter most.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps and the report finds the plot from the address. Where the Lys meets the Dora, flood hazard deserves close attention, and on the steep slopes landslide hazard: both are checked at the exact spot.
