Sleep doesn’t always come easy when you’re living in a beautiful dream. Earlier this month, I spent a night tossing and turning, overwhelmed by an enchanting 13th-century stone house on the edge of Civita di Bagnoregio, a deserted hilltop town about 75 miles north of Rome. I booked it on Airbnb...Civita may be the most popular of the over 20,000 ghost towns in Italy today. Built by the Etruscans in the 7th century BC as an enclave away from the malaria-infested lowlands, Civita been been ravaged by earthquakes, landslides, and storms since the 1300s, with climate change accelerating its decay. Civita has also lost nearly all its residents except for less than 10 people who cling to the dream of living in the crumbling town. Even solo travelers staying at Casa d’Artista would give the town a measurable population boost during their stay..
