Origin and history
The church of Saint-Hippolyte de Bonnay, located in the department of Saône-et-Loire, is an 11th-century construction by the Clunisian monks (order of Saint Benedict). It is one of the first fortified churches of Burgundy, conceived as a defensive rallying point on a height overlooking the plain of the Saône. Its strategic location, 30 metres above Aynard ford, made it a visible landmark from a distance, reinforced by massive stone walls and a bell tower-dongon.
The fortification of the church, authorized by the Lord of Brancion, began in 1214 under the impulse of the monks themselves, contrary to the subsequent practices where the local populations took charge of this work. The bell tower was transformed into a master tower with arches, and a creneled wall surrounded the building. Although probably destroyed in the 16th century, its ruins retain traces of this defensive architecture, such as the two towers accompanying the bell tower and the apsidioles in the hemicycle.
Ranked a historic monument in 1913 after an alert from the Académie de Mâcon in 1912, the church was then described as a "in danger" building. The current remains partially reconstruct his original plan: a nave with three vessels, a transept with crumbs, and a vaulted choir in broken hanger. Its dimensions (26.9 m long, 12.2 m wide at transept) and its architectural elements, like the bays in the middle of the bell tower, testify to its past importance.
The church Saint-Hippolyte illustrates the influence of the Clunisian order in Burgundy, combining religious and defensive functions. Its gradual abandonment reflects the upheavals of the 15th and 16th centuries, when many religious buildings were destroyed or altered. Today, the ruins are preserved by local associations, such as Le Renouveau de Saint-Hippolyte, and studied for their role in regional history.
