Gorreto, the last Ligurian stretch of the Val Trebbia

The SS45 road linking Genoa and Piacenza follows the Val Trebbia for a long way, and Gorreto is one of the last Ligurian villages before the valley crosses into Emilia. The centre, at around five hundred and thirty metres, lies close to the river, with stone houses squeezed between road and hillside; the rest of the municipality is hamlets on the slopes and woodland.

For buyers, Gorreto offers Apennine mountains within reach of Genoa, but the journey time has to be factored in: the road is long and winding, and everyday services are in the larger towns of the valley. Many houses are second homes or family houses left empty for part of the year. Before making an offer, check the roof, damp, services and, for houses near the Trebbia, their position in relation to the river.

In 2023 there were 92 residents, against 107 at the 2011 census, a fall of 14.0%. The population is elderly: over-65s make up 52.2%, against 29.1% for the metropolitan area of Genoa, and the estimated average age is 61.1. Declared incomes are well below the provincial average.

Gorreto is in seismic zone 3, on the scale set by the Civil Protection Department, as are 64 of the 67 municipalities in the Genoa area, with an expected ground acceleration of about 0.103 g. For a stone building, ask whether the roof and floors have been strengthened.

River and slopes are the issues to check: the report reads the official flood and landslide maps at the exact address and, with the Revenue Agency (Agenzia delle Entrate) cadastral maps, finds the land parcel.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
