Piedimonte San Germano, home of the Cassino car plant
People talk about the Cassino car plant, but few realise that the factory actually stands in Piedimonte San Germano, the next municipality along. The old village sits on the lower slopes of the mountains west of Cassino, while down on the plain lie the industrial zone and the housing built in recent decades. The plant has shaped the town: many residents work there or for its suppliers.
The centre was almost flattened in the Second World War, when the area lay on the front line, so most buildings date from after the war. Buyers will find houses from the rebuilt village, and small apartment blocks and detached homes on the plain, often close to busy roads and industrial sites. Cassino is a few kilometres away, with its station on the Rome-Naples line and its exit on the A1 motorway. Climate zone C, with incomes just below the provincial average.
The town is growing and young, which is unusual in the province of Frosinone. In 2023 Istat, the national statistics office, counted 6,297 residents, up 4.3% on 2011; the average age is 43.3 against 46.8 in the province, and over-65s make up 20.2% against 25.4%. Foreign residents account for 5.9%.
The Cassino area is earthquake country. Italy's Civil Protection Department places Piedimonte San Germano in seismic zone 2, like 59 municipalities in the province, while 30 are in zone 1; the expected ground acceleration in the built-up area is about 0.195 g, a medium-high value. Many houses date from the post-war rebuilding and followed the rules of the time, so before buying ask for the design date, any surveys and details of structural work.
Landslide hazard on the hillside and flood hazard near watercourses on the plain change from one address to another, and the report checks them for the exact spot. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the address leads to the plot.
