The Church of Saint-Éloi-Saint-Jean-Baptiste is believed to have originally been the chapel of the Château de Couvé, the first known mention of which dates back to 1215. This château belonged to the Abbey of Saint Père de Chartres. The layout of this chapel is currently unknown. Observing the architectural features of the current church allows us to place its construction between the 15th and 16th centuries. Improvement and modernization work were undertaken in the second half of the 18th century when Louis XV offered the Crécy estate to the Marquise de Pompadour: enlargement of the medieval windows, construction of an altarpiece forming a sacristy, a choir enclosure, and a gallery that could replace an older structure providing access to the attic. During this work, it is assumed that some of the bell tower's supports were removed to free up the nave and harmonize the interior spaces. After a prosperous period, the 19th and 20th centuries saw a slow deterioration of the building, despite some maintenance work being carried out on the roofs and other parts of the church that required it. It was only in 1901 that major work was undertaken, with the repair of the bell tower roof. This was followed in 1925 by work to consolidate the bell tower structures and repair the roofs of the western part of the nave. The bell tower and spire are tilting significantly to the south, linked to a failure of the old supports and the deterioration of the supporting structures, requiring urgent safety and restoration work.
