Velletri, the Castelli Romani and the vineyards towards the plain

Velletri is one of the Castelli Romani, the hill towns south-east of Rome, on the southern side of the Alban Hills facing the Pontine plain. It is a wine town, with a designation of origin bearing its name, and an old one: the family of Octavian, the future emperor Augustus, came from here.

The centre stands at around 330 metres, around the Torre del Trivio and the cathedral of San Clemente. All around spreads a countryside of vineyards, olive groves and scattered houses, running down towards Cisterna di Latina. The Rome-Velletri railway comes right into town and the Via Appia crosses it, so Rome is within reach even without a car.

Buyers choose between the centre, with old buildings and sloping streets, the newer districts on the edge, and the rural contrade. Out in the contrade, houses were often built in stages and services are far away, so check planning compliance, road access and connections to mains water and sewers before making an offer.

At the end of 2023 Velletri had 52,862 residents, up 1.1% on 2011, with an average age of 45.6. Foreign residents make up 9.8%. There are 53 recorded schools, more per resident than the provincial average, while declared incomes remain below those of the metropolitan city of Rome.

The Alban Hills are a dormant volcano that now and then produces swarms of small tremors. Velletri is in seismic zone 2 on the Civil Protection map, with expected ground acceleration of about 0.162 g; for an older building in the centre, find out whether its structure has been assessed. The Revenue Agency (Agenzia delle Entrate) maps cover the municipality and the report finds the plot, while landslides on the slopes and flooding along the ditches are checked for the address.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.162 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Velletri, 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.
