The Historic Centre of San Gimignano sits on a height of land, dominating the surrounding landscape. The Historic Centre of San Gimignano is a cultural site of exceptional value, since it has treasured its architectural homogeneity and its original urban layout. In addition, the historic town is under risk of seismic activity in the region and landslides on the hill. Specifically, the historic centre has maintained intact spaces, volumes and decorations within the medieval layout, due to current regulations which strictly forbid replacements of and alterations to historic buildings. San Gimignano is managed by a multidisciplinary team representing different levels of government coordinated by the municipal administration.
