The history of the Italian city of Civita di Bagnoregio dates back more than three thousand years since the Etruscan times. At the time of its founding, they had no idea that the site, located a hundred kilometers from Rome, lies on the border of the Volsini volcanic crater in a place with a highly unstable subsoil. In the long run, and in recent years more and more often, it has been facing extensive erosion of clayey soil, as a result of which it is gradually disintegrating. Landslides also resulted in gradual depopulation, in 2011 alone less than twenty permanent residents lived here. Geologists have been working for decades to consistently map and ensure unstable subsoil. As part of increasing the protection of the city and securing financial support for securing the subsoil, Italian conservationists proposed inserting the city and the surrounding landscape on the UNESCO World Heritage List. Whether the monument will be included in the list should be made clear in July this year, when a UNESCO committee meeting will take place.
