Origin and history

The church Saint-Jean-de-la-Chaîne, located in Châteaudun in Eure-et-Loir, finds its origins in the sixth century according to tradition, where Saint-Aventin founded a first place of worship dedicated to Saint John. The oldest remains still visible today, such as the northern absidiole and part of the choir, date back to the eleventh century, while the southern absidiole and the nave were built in the twelfth century. These Romanesque elements testify to the first major phase of the building, before subsequent transformations.

In the 15th century, extensive work was undertaken to raise the walls, significantly altering the medieval structure. The bell tower, characteristic of flamboyant Gothic architecture, was added in the 16th century, thus completing the major construction campaigns. The church, originally linked to the abbey of the Trinity of Vendôme, was classified as a Historic Monument in 1907, including its 16th century portal, a vestige of the ancient Saint John cemetery. This portal, in retreat from the building, illustrates the evolution of the designated funeral site.

Among its remarkable pieces is the 18th century painting, The Wedding of Cana, painted by John II Restout (1692–1768). Ranked Historic Monument in 1906, this painting adorns the north arm of the transept, highlighting the artistic and religious role of the building throughout the centuries. The architectural complex, owned by the commune, thus reflects almost a millennium of religious and heritage history in the Centre-Val de Loire.
