Borgo San Lorenzo, the Mugello's main town on the Sieve
The Mugello is the green basin north of Florence, ringed by the Apennines and crossed by the river Sieve, and Borgo San Lorenzo is its main town. It has the area's hospital, secondary schools and many public offices, so people from surrounding villages come here for services and work. The historic centre, on flat ground near the river, keeps some of its old gates; residential districts and small industrial areas have spread around it, while the hills are dotted with isolated houses, farms and agriturismo holiday farms.
The link with Florence is the first thing to weigh up. The Faentina railway connects Borgo San Lorenzo with Florence in one direction and Faenza in the other, and another line runs down to Pontassieve. By car the road to the city has to cross the hills, so commuters should expect journeys longer than the distance suggests. On the valley floor near the Sieve and its tributaries the report checks flood hazard, and on the slopes landslide hazard.
In 2023 there were 18,276 residents, up 2.4% on 2011 according to Istat, the national statistics office. The estimated average age of 46.7 and the share of over-65s, 25.9%, are close to the metropolitan average. Foreign nationals make up 9.8%. Schools and healthcare are denser than the provincial average, as you would expect in a service centre: 0.93 healthcare sites per 1,000 residents against 0.76. Declared incomes are below the provincial average.
The Mugello is one of Tuscany's earthquake areas and was hit by a strong quake in 1919. Borgo San Lorenzo is in zone 2 of the Civil Protection Department's classification, like 12 other municipalities in the province, while 28 are in zone 3; expected ground acceleration in the built-up area is about 0.201 g, fairly high. For a stone house or a block built before the recent rules, ask for the design year, structural checks and any strengthening work. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report finds the land parcel from the address.
