Ottone, the upper Val Trebbia on the Ligurian border

At the far end of the province of Piacenza, where the Val Trebbia reaches the border with Liguria, Ottone is a mountain municipality made up of a main village and many hamlets spread over the slopes. The SS45, the road linking Piacenza to Genoa along the river Trebbia, runs along the valley floor and remains the main link to both cities. In summer the river and woods draw tourists and second-home owners.

It is a very elderly community. In 2023 there were 430 residents, 24.6% fewer than the 570 of 2011. The estimated average age is 57.6, against 46.7 for the province, and over-65s make up 43.0%. Households average 1.50 people, a sign that many live alone. Foreign residents account for 11.2%. Declared incomes are below the average for the Piacenza area.

Buyers in Ottone are usually looking for a stone summer house or a quiet retreat. In the higher hamlets roads are narrow and can be difficult in winter; houses need careful checks (roof, walls set against the slope, services, septic tanks). The report measures the distance from the address to the pharmacy, shops and schools.

All 46 municipalities in the province of Piacenza are in seismic zone 3 of the national classification kept by the Civil Protection Department; in Ottone the expected ground acceleration in the built-up area is about 0.106 g. In a valley like this, landslides on the slopes and floods on the Trebbia and its side streams weigh more, and they should be checked on the official maps for the exact location of the house.

The Revenue Agency (Agenzia delle Entrate) publishes Ottone's cadastral maps, and the report traces the address back to its land parcel.
