Protection areas related to the easements of historic monuments (AC1) listed and classified in Charente.

Surface objects of protection areas related to easements of category AC1 (historical monuments) as defined by the Heritage Code Article L621-2
The basis of an easement is the geographical area within which the easement applies.
Any other building, naked or built, visible from the first or visible at the same time, and situated within a perimeter not exceeding 500 metres, shall be considered to be within the field of visibility of a building classified or proposed for classification. Exceptionally, this perimeter can be extended to more than 500 metres. A decree of the Conseil d’État, made after the opinion of the Higher Commission of Historical Monuments, will determine the monuments to which this extension applies and define the scope of protection specific to each of them.
When drawing up or revising a local urban planning plan, the 500-metre perimeter may, on the proposal of the architect of the Buildings de France and after the agreement of the municipality, be modified so as to designate sets of buildings and spaces that contribute to the environment of the monument in order to preserve their character or contribute to improving their quality. The perimeter is subject to public investigation in conjunction with the local planning plan. It is annexed to the local planning plan under the conditions laid down in Article L. 126-1 of the Urban Planning Code.

本数据集涵盖《遗产法典（Heritage Code）》第L621-2条所定义的AC1类（历史遗迹）地役权相关保护区的地表实体。
地役权的适用基础为其效力所覆盖的地理范围。
任何其他建（构）筑物，无论为裸露场地还是已建成实体，若可从该已分类或拟分类建（构）筑物的视角观测到，或与之同时处于可视范围内，且位于不超过500米的范围之内，则应被纳入该建（构）筑物的可视保护范畴。例外情况下，该范围可扩展至500米以上。经法国历史遗迹高级委员会（Higher Commission of Historical Monuments）审议后，法国国务委员会（Conseil d’État）可颁布政令，明确可适用该范围扩展条款的历史遗迹，并为每处遗迹制定专属的保护范围。
在编制或修订地方城市规划方案时，经法国国家古迹建筑师（Architect of the Buildings de France）提议并征得市镇政府同意后，可对该500米范围进行调整，以划定有助于保护历史遗迹风貌特征或提升其周边环境品质的建（构）筑物群与空间范围。该范围需与地方规划方案同步开展公众征询程序，并按照《城市规划法典（Urban Planning Code）》第L.126-1条规定的条件，作为附件纳入地方城市规划方案。
