Map Viewing Service (WMS) of the dataset: Historical (linear) monuments generating AC1 easements, in Eure-et-loir (28)

The generator of a public easement is a geographical entity whose nature or function induced, by virtue of regulations, constraints on the way the land is occupied on the surrounding land.
The disappearance or destruction on the site of the generator does not result in the removal of the easement(s) associated with it. Only a new act of annulment or repeal by the competent authority may legally remove the effects of the easement(s) in question.

Grade AC1 easements relate to easements for the protection of listed or registered historic monuments: — Classification under historical monuments: these easements relate to buildings or parts of immovables whose conservation is of a public interest from the point of view of history or art. Owners of classified buildings may not carry out restoration, repair or alteration work without the prior authorisation of the regional prefect or the Minister responsible for culture. — Inscription as historical monuments: these easements relate to immovables or parts of immovables 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 consent of the prefect of the region. — Buildings backed by classified buildings and buildings located in 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 shall be considered as a backed building. Any part not protected under the historical monuments of a partially classified building shall be considered as a backed building. 2. Any other building, naked or built, visible from the first or visible at the same time as it is situated within a perimeter determined by a distance of 500 m from the monument shall be considered to be within the field of visibility of a classified or registered building. This 500 m perimeter can be modified or adapted: • the appropriate protection perimeter (PPA): where an unprotected building is subject to a registration, classification or classification procedure, the architect of the buildings of France (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 ABB. This resource describes the surface generators of Grade AC1 easements, i.e. right-of-way of monuments or parts of monuments classified or registered or classified and registered

公共地役权（public easement）的供役源实体是一类地理实体，其属性或功能依据相关法规，对周边土地的使用方式施加了限制。
供役源实体在其场地的灭失或毁损，并不会导致与之相关的地役权消灭。唯有主管当局作出新的废止或撤销决定，方可依法消除涉诉地役权的效力。

AC1级地役权（Grade AC1 easements）指为保护列入名录或登记在册的历史遗迹（historic monuments）而设立的地役权：
— 历史遗迹定级类地役权：此类地役权针对的是从历史或艺术角度而言，其保护具有公共利益的建筑物或不动产（immovables）部分。已定级的建筑物所有人，未经大区区长（regional prefect）或文化主管部长的事先批准，不得开展修复、修缮或改建工作。
— 历史遗迹登记类地役权：此类地役权针对的是虽未达到即时定级申请标准，但具备足够历史或艺术价值、值得予以保护的不动产或其部分。已登记不动产的所有人，未经事先申报不得进行任何改动；未经所在大区区长的事先同意，不得核发任何规划许可（planning authorisation）。
— 依托定级建筑物的建筑及位于定级/登记建筑视野范围内的建筑：
1. 凡在立面、地面或地下与定级建筑物直接毗邻的建筑，均视为依托建筑。部分定级建筑物中未受历史遗迹保护条款覆盖的部分，亦视为依托建筑。
2. 任何其他已建成或待建的建筑，若可从该历史遗迹直接观测到，或虽不可直接观测但位于距该遗迹500米范围内的区域，均视为处于定级或登记建筑的视野范围内。该500米保护范围可予以调整或适配：
• 适宜保护范围（PPA, appropriate protection perimeter）：若某未受保护建筑正处于登记、定级或定级申请程序中，法国建筑遗产保护建筑师（architect of the buildings of France，ABF）可提出适配该建筑属性及其周边环境的保护区域方案。
• 调整后保护范围（PPM, modified perimeter of protection）：经法国建筑遗产保护建筑师（ABF）提议，可对历史遗迹周边划定的保护范围进行调整。

本数据集详述了AC1级地役权的地表供役源实体，即针对已定级、已登记或同时定级并登记的历史遗迹及其部分区域所设立的地役权。
