About Châteaudun
The Mairie de Châteaudun is the municipal institution responsible for administering the commune of Châteaudun, located in the Eure-et-Loir department, in the Centre-Val de Loire region of France. Situated on the banks of the Loir river, the commune occupies a geographical crossroads position between the Perche, Beauce and Val de Loire areas, which has historically shaped its urban and economic development. The mairie serves as the seat of local executive authority, led by the mayor and the municipal council, elected through direct universal suffrage as part of French municipal elections.
Châteaudun has a long history, marked by the presence of a comital castle overlooking the town, reflecting its strategic importance during the Middle Ages, particularly as a stronghold of the counts of Dunois. The town underwent successive phases of reconstruction, notably following destruction during historical conflicts, which contributed to shaping its current urban fabric, blending older heritage elements with more recent developments. This history has given the commune a locally recognized architectural and cultural heritage, around which part of its identity and tourism activities are organized.
In terms of its responsibilities, the Mairie de Châteaudun exercises the standard powers granted to French communes: civil registry, urban planning, management of public facilities, social action, maintenance of local roads, as well as support for cultural, sporting and community activities. It also oversees primary schools and local services for residents. The commune additionally participates in intercommunal cooperation with neighboring authorities to implement broader territorial policies, particularly regarding planning, economic development and shared public services.
The website ville-chateaudun.fr is the official institutional site of the commune, providing administrative, practical and cultural information along with procedures and services intended for residents and visitors.
