…Lago di Bolsena, that is. Just a 20-minute drive from Orvieto, this oval-shaped crater lake (with a quaint medieval village) was formed from a volcanic eruption 370,000 years ago. Geologist believe that a piece of the volcano was catapulted nearly 30 km and landed at the site that Orvieto was later built (hence the town’s nickname “la Rupe). Etruscans found the volcanic ‘tufo’ perfect for digging wells and caves…and the rest is history! Find out more about Orvieto and its surrounding sites when you visit! Like! Share! Visit!
