Osimo, the hilltop town between the Conero and the Musone valley
Osimo stands on a hill at around 260 metres, south of Ancona, between the Musone valley and the hills that run down to Monte Conero. The upper town keeps its walls, its cathedral and the caves dug beneath the houses, some of which can be visited. At the foot of the hill the municipality spreads into lowland districts such as Osimo Stazione, Campocavallo, Padiglione and San Biagio, which have grown with new housing, workshops and industry.
Buyers choose between the upper town, with old palazzi, sloping streets and limited parking, and the valley districts, which are more practical and modern. Ancona is a short drive away, and Osimo-Castelfidardo station on the Adriatic railway is down in the valley.
Osimo is growing: 34,774 residents in 2023 according to Istat, the national statistics office, up 2.3% since 2011. It is younger than the province of Ancona, with a mean age of 45.5 against 47.2 and 23.4% over 65 against 26.2%. Households average 2.42 people and foreign residents make up 6.4%. Declared incomes match the provincial average.
All 47 municipalities in the province are in seismic zone 2 of the Civil Protection classification, Osimo included, with an expected ground acceleration here of about 0.183 g. The 2016 earthquake in inland Marche made many owners more careful: for a building in the upper town, ask whether seismic upgrading has been done and under which permits; for a villa in the lowland districts, ask for the year of construction and the structural design.
In the Musone valley flood hazard needs a close look, and on the hillsides landslide hazard does. The report checks both at the exact spot, using the land parcel from the Revenue Agency's cadastral maps.
