Ronciglione, Lake Vico and a town on the tufa

Ronciglione lies in the Cimini hills south of Viterbo, on the rim of the basin of Lake Vico, a volcanic lake protected as a nature reserve that the town shares with Caprarola. The old centre runs along a ridge of tufa with ravines on either side, and the town is known across Lazio for its carnival.

The surrounding countryside is hazelnut country: the Cimini hills are one of Italy's main growing areas, and the orchards come right up to the houses. Viterbo is about twenty kilometres away, and Rome roughly an hour's drive along the Via Cassia. The medieval core has tall, narrow houses, many needing work, with steep stairs and little room for a car; outside the walls there are newer districts, country houses and, towards the lake, holiday homes.

In 2023 there were 8,429 residents, up 1.5% on the 8,308 of 2011, according to Istat, the national statistics office. The estimated average age (47.8) and the share of over-65s (26.3%) are close to the provincial figures. Foreign residents make up 12.0%, a high share, and households are small, 2.02 people on average.

In the province of Viterbo, 40 municipalities are in seismic zone 2 of the Civil Protection classification; Ronciglione is one of the 20 in zone 3, with expected acceleration of about 0.091 g. At over four hundred metres, winters are cool and damp. In the tufa houses of the centre, check damp, roofs and any work on the walls, and ask about work done on the adjoining buildings.

The edges of the tufa ravines are the sensitive point: the report reads the landslide and rockfall hazard maps at the exact address, and flood maps along the streams. With the cadastral maps published by the Revenue Agency (Agenzia delle Entrate), it identifies the plot.

Key points

  • Cimini hills, on the rim of Lake Vico, among hazelnut orchards.
  • Population up 1.5% since 2011, foreign residents at 12.0%.

Earthquakes

For Italy's Civil Protection Department, Ronciglione is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Only 20 of 60 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.091 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.

How built-up it is

According to the ISPRA map, the estimated radon emission in the municipality is very high. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Ronciglione, and one more has been cleaned up or closed. The report tells you whether one is close to the address.

Landslide and flood hazard changes from one street to the next even within Ronciglione: the report checks the address against the ISPRA maps.

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 57 inhabited census areas in Ronciglione. Half of the residents live in areas scoring 70 or more.
