Ollomont, a side valley of the Valpelline

Ollomont has gained residents since 2011, which is not a given for a municipality above thirteen hundred metres. The village lies in a side valley of the Valpelline, north of Aosta, closed at its head by the mountains along the Swiss border. Its territory is made up of small hamlets, hay meadows, larch woods and high pastures; copper was once mined in the valley, and traces of the old mines can still be seen.

According to Istat, Italy's national statistics office, there were 165 residents in 2023, 7 more than the 158 of 2011, a rise of 4.4%. With numbers this small a few families make the difference, but the trend is still upward. The estimated average age is 48.3, slightly above the 47.0 of the Aosta Valley, and over-65s make up 23.6%. Declared incomes are in line with the regional average.

Aosta is the reference for work, secondary schools, the hospital and public offices, and the road runs down through the Valpelline. In climate zone F winter is long, so buyers should estimate heating costs carefully, check insulation and windows and ask how snow is cleared on the road to their hamlet. On old stone and timber houses, the roof is the first thing to inspect.

Like all 74 municipalities in the Aosta Valley, Ollomont is in seismic zone 3 on the Civil Protection Department's scale, and the expected ground acceleration in the built-up area is about 0.117 g. In high mountains, slopes, streams and gullies matter more, and the report checks the official landslide and flood maps at the precise address. Revenue Agency cadastral maps are published here too, and the report links the house to its land parcel.
