Rapolano Terme, travertine quarries and hot springs near Siena
Rapolano Terme lies on the eastern edge of the Crete Senesi, the clay hills east of Siena, where they give way to the Val di Chiana. The town is known for two things that come from the same ground: thermal waters, with spa establishments open to the public, and travertine, a pale building stone quarried for centuries around the town and towards Serre di Rapolano.
There are two centres. Rapolano itself has its old core on the higher ground and newer housing spreading towards the Siena-Chiusi railway, which stops here. Serre di Rapolano is a hilltop village of its own. Between them are farms and scattered farmhouses, many restored as holiday homes or for letting to tourists. With a farmhouse, check the access road, the water supply and the drainage: away from the villages these are often not connected to the public network.
According to Istat, the national statistics office, there were 5,107 residents in 2023, a change of -0.4% since the 2011 census. The average age is 47.8, against 47.6 for the province of Siena, and over-65s make up 26.8%. Households have 2.20 people on average and foreign residents account for 11.6%.
The Civil Protection Department places Rapolano in seismic zone 3, along with 30 other municipalities in the province, while 4 are in zone 2. The expected ground acceleration in the built-up area is about 0.135 g. In stone village houses and farmhouses, the question for the seller is about floors and roof: whether they have been redone, when, and with which permits.
The Revenue Agency publishes the cadastral maps for the municipality, so the report can go from the address to the land parcel. On the clay of the Crete, slopes can shift, and water collects along the ditches after heavy rain, so landslide and flood hazards are read for the individual address.
