Diano San Pietro, olive groves behind Diano Marina

A few minutes' drive takes you from the seafront at Diano Marina to the olive groves of Diano San Pietro. The village lies in the valley climbing inland from the coast, in the Gulf of Diano, with its centre low in the valley and its hamlets spread across the hills among terraces of olive trees.

It is a common choice for people who work on the coast but want different prices and more space than by the sea, and for buyers of a country second home with a view. Houses on the slopes are often reached by narrow, steep lanes, and many old farm buildings among the olives have been restored or are waiting to be. In those cases, check vehicle access, utility connections and the state of the dry-stone walls holding up the terraces. The climate is mild, zone C. Declared incomes remain below the provincial average.

There were 1,094 residents in 2023, almost the same as in 2011 (1,101). The average age is 49.5, against 48.7 in the province, and 28.9% are over 65. Foreign nationals make up 10.7% of residents.

In the province of Imperia earthquakes need taking seriously: Diano San Pietro is in seismic zone 2, like 29 other municipalities, with an expected ground acceleration of 0.150 g. For a stone house on the hillside, a structural survey before completion is money well spent.

Slopes and streams make it worth checking the address against the official landslide and flood maps, which the report does automatically. The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the whole municipality.
