description Calanchi di Bagnoregio Overview
The Calanchi di Bagnoregio are deeply eroded clay-rich slopes surrounding Civita di Bagnoregio in the Lazio region of central Italy. Rainfall, runoff, and slope failure have carved the soft sediments into narrow ridges and gullies known in Italian as calanchi, while erosion continues to affect the hill supporting the settlement. The landscape is studied for its geology and instability and visited for views of Civita's unusually isolated hilltop setting.
