Au cœur du Dunois, l'église Saint-Hilaire de Châtillon déploie un mariage saisissant entre roman du XIIe siècle et chapelles gothiques flamboyantes du XVIe, rehaussé de peintures murales d'une rare fraîcheur.

Nestling in the quiet market town of Châtillon-en-Dunois, halfway between Chartres and Vendôme, the church of Saint-Hilaire is one of those nuggets of rural heritage that are all too often overlooked on major tourist routes - and all the more precious for it. Listed as a Historic Monument since 1995, it brings together eight centuries of French religious architecture in a single building, offering the attentive visitor an amazingly coherent lesson in stone. What makes Saint-Hilaire truly unique is the creative tension between its two major construction campaigns. The Romanesque core of the 12th century - single nave, semi-circular apse, panelled roof - exudes an austerity that is not coldness but spiritual concentration. Then came the Renaissance, with its ribbed rib-vaulted chapels and late transept, which profoundly transformed the silhouette of the building without betraying its soul. This dialogue between periods is rare in a village church, and it is precisely this contrast that gives Saint-Hilaire its charm. The interior holds a major surprise: wall paintings unearthed during excavation campaigns, covering two distinct periods. Those in the nave, attributed to the 16th century, and those in the arms of the transept, later and classical in style, make up a polychrome ensemble that reminds us that medieval churches were never the bare, white spaces that our imaginations make them out to be. Here, the walls still speak. The western façade, punctuated by four buttresses made of grison - a local stone with a tight grain and a greyish hue - has a sober gravity that invites you to meditate even before crossing the threshold. The gateway, modest in size, is all the more touching because it does not seek to impress, but to welcome. The site is freely accessible from the village, making it an ideal place to stop and reflect during a walk in the Eure-et-Loir region.
Saint-Hilaire has a Latin cross plan, the originality of which lies in the superimposition of two distinct architectural approaches. The original Romanesque structure - a single nave with a narrow nave, a choir and a semi-circular apse - is based on an aesthetic of sobriety and solidity. The walls, built of roussard stone and flint rubble, give the whole a palette of warm, earthy colours that vibrate differently in the light of day. The sober, frontal western facade is punctuated by four grison buttresses that punctuate the surface with an almost musical regularity; the modestly-proportioned portal is framed by discreet mouldings in the Perche Romanesque tradition. The transept and oriented chapels added in the 16th century introduce a late Gothic vocabulary into this Romanesque ensemble. The ribbed stone vaults that cover these spaces - probably with liernes and tiercerons - contrast with the panelled framework of the nave, whose panelling, dated 1561, forms a painted wooden ceiling of great historical and aesthetic interest. This cohabitation of exposed framework and stone vaulting within the same building is a remarkable technical and visual feature. The interior is also enlivened by several registers of wall paintings: the 16th-century decorations in the nave, both figurative and ornamental, interact with the classical compositions of the transept arms, with their more hieratic figures and trompe-l'œil painted architectural frames. Taken as a whole, Saint-Hilaire is a veritable open-air museum of mural painting, accessible in the setting of a deep Dunois village.
