Sant'Ambrogio sul Garigliano, the river plain near Cassino
Here the Garigliano marks the border between Lazio and Campania, and Sant'Ambrogio sits on the Lazio bank, in the south of the province of Frosinone, a short distance from Cassino. The village is low-lying, at around 140 metres, with fields and scattered houses on the plain and the centre on a small rise.
This area lay on the Gustav Line, and in 1944 it saw the fighting for Cassino: many buildings date from after the war, rebuilt or built from scratch. For buyers, that means more reinforced concrete or recent masonry than intact historic centres, so always ask for the design and the structural approval certificate. Cassino is the reference for services, trains and work, and the climate is zone C, with mild winters.
At the end of 2023 there were 872 residents, 12.3% fewer than the 994 of 2011. The average age is 49.6, against 46.8 in the province; over-65s are 30.0% and foreign residents 2.6%. Average declared income is a little below the provincial figure.
For earthquakes, the municipality is in seismic zone 2, like 58 other municipalities in the province, with an expected ground acceleration of about 0.138 g; in the same province, 30 municipalities are in zone 1, the most hazardous. Structural paperwork is still the first thing to check.
Near the river and the drainage channels of the plain, flood hazard matters, and the report checks it on the official maps for the precise address. The Revenue Agency publishes the cadastral maps.
