Origin and history
The former chapel of Boisseleau was originally the church of a Benedictine priory attached to the Saint-Avit Abbey of Châteaudun. The building, built mainly in the 12th century, consists of a Romanesque nave completed by a cul-de-four apse. This medieval heart was completed by a north side, added in the 16th century, which served as a seigneurial chapel. The nave is covered with a panel dating from 1572, decorated with coats of arms attributed to the Abbess of Saint-Avit.
The lower side, erected in 1537, has three glazed spans marked externally by hooked gables, characteristic of flamboyant Gothic architecture. Leabside preserves traces of 16th-century murals, including the Three Marys. These decorative and structural elements illustrate the evolution of the site, from a monastic place to a space combining religious and seigneurial functions.
Ranked among the Historical Monuments since 1973, the chapel bears witness to the links between the priory and the mother abbey of Châteaudun, as well as to the influence of the local sponsors, as evidenced by the coat of arms and the date engraved on the panel. Its state of conservation and architectural details make it a remarkable example of the religious heritage of the Centre-Val de Loire region.
