Seborga, the hill village above Bordighera

Seborga sits at about five hundred metres in the hills behind Bordighera, with views down to the sea and cultivated terraces around the village. It is known for its claim to be an independent "principality", a curiosity that draws visitors but has no legal effect: Seborga is an ordinary Italian municipality, with the same rules for property sales, taxes and land registration as anywhere else. Bordighera, Sanremo and Ventimiglia are a drive down towards the coast.

The old centre is made of narrow stone houses built against each other, with lanes climbing uphill; outside the village there are villas and houses on the terraces. On terraced land, check the dry-stone walls, rainwater drainage and car access. Climate zone E tells you winters at this height are cooler than on the coast.

In 2023 there were 278 residents, 45 fewer than the 323 of 2011, a fall of 13.9%. The estimated average age is 52.5, against 48.7 in the province of Imperia, over-65s make up 34.9% and foreign residents 12.2%. Declared incomes are below the provincial average.

Seborga is in seismic zone 3, like 36 of the 66 municipalities in the province, with expected ground acceleration of about 0.144 g. In a stone house in the centre, what matters is how walls and floors are tied together; for the slopes, the report checks the official landslide maps for the address.

Revenue Agency cadastral maps are published, as for every other municipality in Liguria.

Earthquakes

For Italy's Civil Protection Department, Seborga is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (36 of 66) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.144 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

The estimated average age is 53 years, higher than the province average (49). 35% of residents are over 65 (the regional figure is 29%). Foreign residents make up 12.2% of the population.
