Dolceacqua, the Doria castle and the bridge over the Nervia

Heading up the Nervia valley from the coast at Ventimiglia, you soon reach Dolceacqua: a medieval village huddled below the castle of the Doria family, a humpbacked stone bridge over the stream that Claude Monet painted during a stay on the Riviera, and terraced hills planted with Rossese, the local red wine.

Tourism is noticeable: Overture Maps data list 34 bars, restaurants and cafés, a lot for a village of this size. The population has also grown, with 2,155 residents in 2023 according to Istat, the national statistics office, up 8.3% on 2011. The average age is 46.3, lower than 48.7 for the province of Imperia, and foreign nationals make up 11.9%. Declared incomes are below the provincial average.

Buyers in the old village will find tall, narrow houses with steep stairs, lanes cars cannot reach and often little light on the lower floors; outside the old village and in the countryside there are flats and houses with gardens. In old houses, damp, the roof and the vaulted ceilings are the things to check. The climate is mild, zone C, and the coast, with trains to Genoa and France, is a few minutes away.

Dolceacqua is in seismic zone 3, like 36 municipalities in the province, with expected ground acceleration of about 0.145 g. For an old stone building, ask whether structural work has been done. Near the Nervia and on the terraces the report checks flood and landslide hazard for the address on the official maps and finds the plot on the Revenue Agency (Agenzia delle Entrate) cadastral maps.
