Sasso Marconi, where the Reno and Setta valleys meet
The name honours Guglielmo Marconi, who carried out his first radio experiments at Villa Griffone, in the hamlet of Pontecchio, and is buried beside it. Sasso Marconi covers the stretch of valley where the Setta flows into the Reno, just before the river leaves the Apennines for the plain of Bologna.
For people working in Bologna it is one of the most convenient hill towns. The Porrettana railway has several stops within the municipality, including Sasso Marconi and Pontecchio, and the A1 motorway has a junction right here. The main town and Pontecchio lie on the valley floor along the Porrettana road, while the other hamlets and scattered houses climb the slopes, often on narrow winding roads with colder winters. An isolated house in the hills offers space and greenery but means relying on a car, maintaining private lanes and dealing with snow.
The population is growing slowly, up 2.2% on 2011 according to Istat, the national statistics office, and it is older than the provincial average: estimated average age 48.4 against 46.6, over-65s at 27.6%. Households are small, 2.13 people on average, and declared incomes are above the metropolitan area. There are 1.28 sports facilities per 1,000 residents, against 0.95 in the province.
Landslides are the issue not to underestimate. The slopes of the Bologna Apennines are largely clay and many move slowly: cracks in walls, uneven floors or leaning retaining walls are signs to show a surveyor. The report checks the official landslide maps for the address, as well as the flood maps near the Reno and the Setta.
In the province, 12 municipalities higher up in the Apennines are in seismic zone 2. Sasso Marconi is in zone 3, with an expected ground acceleration in the built-up area of about 0.163 g. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the land parcel can be found from the address.
Key points
- Villa Griffone and the Porrettana railway, with an A1 junction in town.
- Average age 48.4, against 46.6 in the province.
- Clay slopes: landslide hazard to check plot by plot.
- Seismic zone 3, expected acceleration about 0.163 g.
Overview
Sasso Marconi is a municipality in the province of Bologna, in Emilia-Romagna. At the end of 2023 it had 14,868 residents, ranked 15 of 55 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, Sasso Marconi is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (43 of 55) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.163 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 118 inhabited census areas in Sasso Marconi. Half of the residents live in areas scoring 62 or more.
