Criterion (i): Through the unique combination of the natural site and the architecture, the Mont-Saint-Michel constitutes a unique aesthetic success. AuthenticityThe relation between the Mont and the vast surrounding landscape of the bay has remained intact for centuries. The shared governance between the State and the Mixed Syndicate of the Bay of Mont-Saint-Michel, set up in 2006, continues with the body called the Conference of the Bay, chaired by the Prefect of the Normandy region and the two chairpersons of the Normandy and Brittany regions. Its boundary was defined based on a landscape study where the Mont-Saint-Michel, the principal panoramas and the Montjoies are all visible. Furthermore, an area of influence over the landscape of the Mont-Saint-Michel has been defined, exclusive of its major installations and equipment, which completes the system.
