Sant'Andrea del Garigliano, by the river near the Campania border
The name gives the location away. Sant'Andrea del Garigliano sits at the southern tip of the province of Frosinone, close to the Garigliano river and the border with Campania, on a low hill above the plain the river crosses on its way to the Gulf of Gaeta.
Cassino is the town people rely on: it has the hospital, secondary schools, the railway station and the junction for the A1 motorway, which runs to Rome one way and Naples the other. Anyone living here and working elsewhere almost always drives. In the winter of 1943-44 this valley was on the front line, and in the Garigliano villages many houses were rebuilt or altered after the war, so ask in writing for the year of construction and any later work.
The population has shrunk noticeably. In 2023 there were 1,265 residents, down 19.2% on the 1,566 of 2011, which is 301 fewer people, according to Istat, the national statistics office. The average age is 48.8, against 46.8 in the province, and over-65s are 30.7% (25.4% provincially). Households are small, with 2.01 people on average.
For earthquakes, the municipality is in zone 2 of the Civil Protection classification, like 58 other municipalities around Frosinone, while 30 in the province are in zone 1. The expected ground acceleration in the built-up area is 0.123 g. For an older masonry house, a structural check before completion is money well spent.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report goes from the address to the plot. For houses on the flat land near the river, the official flood maps are worth checking.
