Église Saint-Ambroise de Busserotte-et-Montenaille, Catholic church in Busserotte-et-Montenaille, Côte-d'Or, France

Église Saint-Ambroise is a church building showing medieval origins along with later changes, representing a typical rural religious structure. The building has a single nave with twin semicircular windows, a vaulted chancel, and a bell tower featuring double arcades in its design.

The oldest parts of Saint-Ambroise date from the 13th century; the church was altered in the 15th and 18th centuries. It was pillaged and vandalised in 2016, then restored between 2018 and 2020 with support from the Fondation du patrimoine, and was selected for the second Loto du patrimoine in 2019. It was listed as a monument historique on 24 January 1947.

The church is dedicated to Ambrose of Milan, and the seigneurial Sainte-Catherine chapel keeps remains of wall paintings showing the Crucifixion and the apostles against a landscape background. In the choir, 17th-century trompe-l'œil paintings imitate hangings with inscriptions. A funeral band (litre funéraire) is painted on the exterior walls, now plastered over since the restoration.

The church stands on the slope of a steep hillside above the village of Busserotte. Restoration carried out between 2018 and 2020, supported by the Fondation du patrimoine, included exterior rendering that changed the building's appearance. Look for the funeral band painted on the exterior walls, now covered by that render.

The bell is listed as a monument historique, but the sources give no casting date for it. Six funeral slabs from the 13th and 14th centuries are also inscribed, and the choir keeps 17th-century trompe-l'œil paintings of hangings with inscriptions, while the Sainte-Catherine chapel holds remains of murals of the Crucifixion and the apostles against a landscape.
