 Unfortunately, some violent earthquakes significantly destroyed the original structure of the town, among them, the most violent ones were the one in 1352 (measuring 6 on the Richter scale) and the last one, on April 26, 1917.This is the reason why the medieval structure of the town only partially remains today and most of the buildings were built after 1917, like the town hall by Giovanni Michelucci, in the main square of the town.The new town has developed at foot of the hill, where the main street to go either to Arezzo or to Sansepolcro and Umbria runs.
