Porto San Giorgio, the seaside town below Fermo
Porto San Giorgio is the seaside town at the foot of the hill of Fermo: a small, almost entirely built-up municipality squeezed between the beach, the Adriatic railway and the first hills. The seafront with its beach establishments, the marina and the medieval fortress in the old town are what visitors recognise straight away.
The housing market follows the sea. Many flats are second homes used in summer, and between the strip near the beach and the streets towards the hill, prices, noise and neighbourhood life in the colder months all change. Transport links are good, with a station on the Adriatic railway and an A14 motorway exit a few minutes' drive away. For each address the report shows the local price range and the services within walking distance.
In 2023 there were 15,615 residents, down 2.1% since 2011, making up 9.3% of the province of Fermo. The population is old, with an average age of 48.6 against 47.6 in the province and over-65s at 28.9%. Foreign nationals account for 5.8%. Declared incomes are well above the provincial average. There are a great many cafés and restaurants for a town this size, 201, a sign of how much tourism counts.
Porto San Giorgio is in seismic zone 2 of the Civil Protection Department's classification, like the other 39 municipalities in the province, with expected ground acceleration of about 0.181 g. Many seafront apartment blocks were built during the beach-holiday boom decades, before today's seismic rules. Before buying, ask for the design date, any surveys, and the condition of the steel and concrete, which salty air puts under strain.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the land parcel from the address. Near stream mouths and along the coastal strip, flooding and erosion depend on the exact position and are read address by address.
