Monte Romano, open countryside inland from Tarquinia
Monte Romano lies in the hinterland of the Lazio Maremma, on the road linking Vetralla with Tarquinia and the coast. The village sits on a rise at about 230 metres, surrounded by wide, lightly built countryside of pasture, arable land and woods. Viterbo is the provincial capital and reference point, and the sea at Tarquinia is a short drive away.
It is a farming centre, with livestock and country estates, and a straightforward property market: houses in the old centre, recent small blocks on the edges, farmhouses and rural buildings scattered across the land. Prices are lower than on the coast. Declared incomes are in line with the average for the province of Viterbo.
There are 1,854 residents in 2023, down 7.6% on 2011. The average age is 47.5, the same as the province (47.5), over-65s are 28.4% and foreign residents 6.6%. The climate is zone D, mild.
In the province of Viterbo, 40 municipalities are in seismic zone 2 and 20 in zone 3. Monte Romano is in zone 2 on the Civil Protection scale, with an expected acceleration of 0.119 g. For a farmhouse, ask whether the walls and roofs have been strengthened and whether extensions and farm outbuildings are authorised.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here. The report traces the parcel from the address and checks the official landslide and flood maps, useful for farmhouses near ditches and on slopes.
