Origin and history

The church Saint-Hilaire de Châtillon-en-Dunois, located in the Eure-et-Loir department in the Centre-Val de Loire region, is a religious building built mainly in the 12th century. It was part of the Perche-Gouet church group, a region then dependent on the church of Chartres before the erection of Blois in 1697. Its initial architectural features included a single nave, a choir, a semicircular apse, and a panelled frame. The western facade, marked by four foothills in a grotto, is pierced by a modest portal.

In the 16th century, the church underwent major transformations, typical of this period, with the addition of a transept and lateral chapels oriented, covered with vaulted stone. The walls of the frame, dated 1561, bear witness to this phase of renovation. These changes gave the building an original appearance, distinct from other churches in the region. Wall paintings, dated from the 16th century and the classical era, were also discovered in the nave and arms of the transept.

Classified as a historical monument by decree of 29 September 1995, the church is built of russerd stone and flint bellows. Today it belongs to the commune and is located at 3 Place de l'Église, in the new commune of Arrou. Its hybrid architecture, combining Romanesque elements and Renaissance additions, makes it a remarkable testimony to the evolution of religious styles in this region.

The location of the building, although documented, remains of average accuracy (level 6/10 depending on the sources), and its current access (visit, rental, etc.) is not specified in the available data. The sources also mention links with religious heritage observatories and Merimée bases, highlighting its heritage importance.
