Protective zones linked to the easements of category AC1 (Historical monuments) in Eure-et-Loir (28) at 15/01/2026

The plate of a servitude is the spatial field (i.e., the geographical area) within which the servitude applies. Any other building, naked or built, visible from the first or visible at the same time as it and situated within a perimeter not exceeding 500 metres, shall be considered to be located in the field of visibility of a building classified or proposed for classification. Exceptionally, this perimeter can be extended to more than 500 meters. A decree in the Council of State, taken after the opinion of the Higher Commission of Historic Monuments, will determine the monuments to which this extension applies and will delimit the perimeter of protection specific to each of them.When drawing up or revising a local urban planning plan, the perimeter of 500 meters may, on a proposal from the architect of the Bâtiments de France and after agreement of the municipality, be modified so as to designate sets of buildings and spaces that participate in the environment of the monument to preserve its character or contribute to improving its quality. The perimeter is subject to public inquiry in conjunction with the local urban plan. It is annexed to the local urban plan under the conditions laid down in Article L. 126-1 of the Urban Planning Code.
