Monte Compatri, from the Castelli Romani to the Metro C terminus

Monte Compatri is one of the Castelli Romani, the hill towns south-east of Rome. The old centre sits high up, at almost 600 metres, with houses packed tightly around the main church and steep streets; from there the land drops towards the plain along the Via Casilina, where newer districts such as Laghetto have grown in recent decades. The terminus of Rome's Metro line C bears the town's name, Monte Compatri-Pantano, and lies down on the plain.

Choosing a home here means choosing between two ways of living. Up in the town there are flats in old buildings, often without a lift or parking, with cool winters and views over the Roman countryside. Down below, the stock is mostly detached houses and recent small blocks, easier for anyone commuting to Rome by car or metro. Declared incomes are below the average for the province of Rome, though that average is pushed up by the capital.

Istat, the national statistics office, counted 11,757 residents in 2023, up 4.7% since 2011. The population is young: estimated average age 44.6, with over-65s at 19.9% against 22.9% in the province. Foreign residents make up 13.0%. Public transport stops are more frequent than the provincial average, at 0.34 per 1,000 residents against 0.12.

Like nearly all the Castelli, Monte Compatri is in seismic zone 2 of the Civil Protection Department's scale, together with 96 other municipalities in the province. Expected ground acceleration in the built-up area is about 0.169 g. The Alban Hills are volcanic in origin and record small tremors from time to time, so for a masonry house in the old centre it is worth asking what checks have been carried out on walls and floors.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report finds the plot from the address. Between the hilltop town and the districts on the plain, elevation, slope and landslide hazard all change, and the report measures them for the individual house.
