976 Servitude plate AC1 (protection of historical monuments)

The AC1 easements relate to the protection easements of classified or registered historic monuments: — Classification as historical monuments: these easements concern immovables or parts of immovables whose conservation is of public interest from the point of view of history or art. Owners of classified buildings may not carry out restoration, repair or modification work without the prior authorisation of the regional prefect or the Minister responsible for culture. — Inscription as historical monuments: these easements concern buildings or parts of buildings which, without justifying an application for immediate classification, are of sufficient historical or artistic interest to make their preservation desirable. Owners of registered immovables may not make any changes without prior declaration; no planning authorisation may be issued without the prior agreement of the prefect of the region. — Buildings backed by classified buildings and buildings within the field of visibility of classified or registered buildings: 1. Any building in contact with a classified building, in elevation, on the ground or in the basement is considered to be a backed building. Any part not protected as historical monuments of a partially classified building is considered to be a backed building. 2. Any other building, whether naked or built, which is visible to the former or visible at the same time as it is situated within a perimeter determined by a distance of 500 m from the monument, is considered to be within the field of visibility of a classified or registered building. This 500 m perimeter can be modified or adapted: • the adapted protection perimeter (PPA): where an unprotected building is the subject of a registration, classification or classification procedure, the French Building Architect (ABF) may propose a protection area adapted to the nature of the building and its environment. • Modified perimeter of protection (PPM): the perimeter established around a historic monument can be modified on the proposal of the ABF. This resource describes the plates of AC1 towels, i.e. all or part of a building, or a defined perimeter(s) around the monument: • the radius of 500 meters fixed by law, • either a perimeter extended beyond 500 meters or on the contrary reduced (industrial buildings, rural edicules,...) or specific (cone of view, monumental perspective,...), • a perimeter limited to the most sensitive geographical areas or extended to landscape elements located beyond the 500 meters but maintaining a strong relationship with the monument (perspective of a path, landscape setting,...).
