A 1922 law regulated the urbanisation and development of land in this former military zone once it was transferred to the City, and the boundary of the servitude was formally surveyed and marked. The dataset records the location and characteristics of these historical boundary markers, providing a geographic reference for urban planning, heritage studies, and research into the city's former military land-use restrictions.”La loi de 1922 fixait un cadre au développement et l’urbanisation des terrains de l’ancienne zone militaire cédés à la Ville.
