The church of Châteauneuf is mentioned for the first time in 1303 in a recognition of cens (rent) of a house located in front of the church of the city of Châteauneuf (ecclesie Ide ville Castri novi). If the first textual mention dates back to the beginning of the 14th century, the current building was built at the very end of the 15th century by Philippe Pot, an important personage of the court of the Dukes of Burgundy who ordered important works, at the castle but also in church. Dendrochronological analysis has determined that the structure of the building was put in place from 1491. Originally, Châteauneuf depended on the cure of Vandenesse-en-Auxois, in. below the plateau. The church of Saint-Philippe-et-Saint-Jacques probably became the parish capital shortly before 1572. The church, with a Latin cross plan, is sober and presents classic Gothic architecture from the end of the Middle Ages. The single nave, covered with ribbed vaults, is flanked by two chapels opening onto the third bay: the seigneurial chapel of Saint-Joseph to the north and the chapel of the Virgin (previously the chapel of Saint-Jean) to the south. Various alterations and restorations since the end of the 18th century have slightly modified the medieval building, in particular the bell tower (destroyed by lightning in 1779) or the chapel of the Virgin in 1890. The paintings of this chapel and the choir are from this era. The last restoration dates from 2011
