San Giorgio a Liri, on the Liri plain near Cassino
The river gives the town its name and shapes its land. San Giorgio a Liri lies in the southern part of the province of Frosinone, on the Liri plain a short way from Cassino, at a low elevation of around 40 metres. It is an area of fields, scattered houses and small nearby towns, with Cassino as the reference point for work, secondary schools, the hospital and the junction onto the A1 motorway.
The location suits people who travel towards Rome or Naples: the A1 is close and quick to reach. Houses are mostly rebuilt or built after the Second World War, since this part of the valley was badly hit, and today the town is made up of detached houses, low blocks and rural homes with land. Outdoor space is easy to find.
Istat, the national statistics office, counted 2,959 residents in 2023, down 6.5% since 2011. The average age of 45.9 is a little below the provincial 46.8; over-65s make up 24.6% and foreign nationals 6.2%. Declared incomes are slightly below the provincial average.
San Giorgio a Liri is in seismic zone 2, with an expected ground acceleration of 0.129 g. For a post-war house, find out how it was built and whether the floors have been strengthened. The thing to check most carefully is how close the property is to the Liri and the drainage channels of the plain: the report checks the official flood maps for the address. Climate zone C brings mild winters.
