Olevano Romano, Cesanese wine and the painters' village

Olevano Romano stands above five hundred metres on the slopes of the Prenestini mountains, on the border with the province of Frosinone. The town climbs the hillside below the remains of its castle, surrounded by vineyards and olive groves: this is the home of Cesanese di Olevano Romano, a red wine with its own designation of origin. In the nineteenth century many northern European artists, especially Germans, came here to paint the landscape; the Serpentara oak wood, linked to that period, still belongs to a German institution.

Rome is about fifty kilometres away, and the journey is almost always made by car. Olevano mainly appeals to people looking for a village house with a view, often as a second home, and to those working around Palestrina, Valmontone and Colleferro. The old centre is steep, with stepped lanes and tall, narrow houses: before buying, think about car access, parking and how building materials would get in for any work.

There were 6,353 residents at the end of 2023 according to Istat, the national statistics office, down 5.8% since 2011. The average age of 47.0 is above that of the metropolitan area, over-65s make up 24.2% and foreign residents 9.5%. Declared incomes are well below the provincial average, which Rome pushes up.

Olevano is in seismic zone 2 on the Civil Protection scale, like 97 of the 121 municipalities in the metropolitan area, with an expected ground acceleration of about 0.154 g. In the stone houses of the centre, often built in stages and leaning on one another, how a building behaves in an earthquake also depends on its neighbours: a surveyor can tell you whether it has been strengthened and what it would need.

On the hillside the report checks the landslide maps for the individual address; the cadastral maps are published, so it can go from the address to the land parcel.

Earthquakes

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.154 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Olevano Romano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
