Trevignano Romano, on the north shore of Lake Bracciano

Trevignano Romano's houses run down the hillside to the water on the northern shore of Lake Bracciano, the large volcanic lake north-west of Rome. Above the old village stand the ruins of its castle; below runs the lakefront, with restaurants and small beaches. The municipality lies within the Bracciano-Martignano regional park, and much of it is hills, woodland and fields on the rim of the old crater.

People buy here for the lake and the quiet, and accept being away from the railway: the line to Rome runs along the opposite shore, with stations at Anguillara and Bracciano, so from Trevignano people drive into the city. Many homes are holiday homes or belong to people who have moved out from Rome: detached houses with gardens on the hills, flats in the old village and a few farmhouses. The highest prices are for lake views. Declared incomes are below the average for the metropolitan area of Rome.

Tourism shows in the figures: 13.09 bars and restaurants per 1,000 residents, against 4.96 in the province. Residents have grown by 10.1% since 2011, to 5,807 in 2023 according to Istat, the national statistics office, and they are older than average: a mean age of 48.7 against 46.0, over-65s at 27.8%. Households are small, 1.94 people on average, and foreign residents make up 14.2%.

In the metropolitan area of Rome, 97 municipalities are in seismic zone 2 and only 24 in zone 3 on the Protezione Civile scale (Italy's Civil Protection Department); Trevignano is one of the latter, in zone 3. Expected acceleration, about 0.072 g, is low for Lazio. In the old village, with tufa houses sharing walls, it is still worth asking what work has been done on roofs and floors.

On the crater slopes, gradient and landslide hazard need reading house by house, and for homes closest to the shore the lake level matters too. The report does this at the address, starting from the Revenue Agency (Agenzia delle Entrate) cadastral maps, which are available for Trevignano.

Key points

  • North shore of Lake Bracciano, inside the regional park.
  • No station: the railway to Rome runs along the far shore.
  • 5,807 residents, up 10.1% since 2011.
  • Seismic zone 3, like only 24 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Trevignano Romano is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3B. Only 24 of 121 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.072 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.
