About Montlhéry
Montlhéry is a French commune located in the Essonne department, in the Île-de-France region, administered by a municipal government that constitutes a basic local authority under French law. It is affiliated with an intercommunal cooperation body and forms part of the administrative organization of the Essonne department, within which it exercises shared competences. Its territory lies in the southern part of the Paris metropolitan area, close to major transport routes connecting Paris to the rest of Île-de-France, a position that has historically favored its development and gradual integration into the regional urban fabric.
The history of Montlhéry is ancient and marked by the presence of a medieval fortress, of which a tower survives today as an emblematic remnant that played a strategic role during feudal conflicts, notably during the Battle of Montlhéry in the fifteenth century. The commune subsequently developed around this historic core, retaining a distinctive old town center while undergoing more recent urbanization linked to its geographic position. In the twentieth century, the municipal territory also became home to a racing circuit that gained recognition in the field of automotive testing, contributing to the reputation of the Montlhéry name beyond the local area.
As a local authority, the commune carries out the traditional responsibilities assigned to French municipalities: managing public facilities, urban planning, civil registration, local social action, maintenance of communal roads, and organization of associative and cultural life. It exercises these competences within the legal framework set by the General Code of Local Authorities, in coordination with intercommunal, departmental, and regional levels. The website montlhery.fr is the official institutional website of the commune, presenting administrative, practical, and municipal information intended for residents and users.
