Once a branch of Grancey-le-Château, it was established as a parish in 1803, with Villemoron as its branch. Shortly afterwards, however, it was returned to its original state and became a simple branch of Lamargelle until 1869, when it became a branch of Villemoron. This isolated church with its bell tower and porch has a proud appearance and appears to have been built in the second half of the 12th century. Legend has it that, at the time it was built, the local lord, fearing that the church's spire would overtake his house, opposed the construction of the church, but to no avail. Traces of walls being torn away on the north side suggest the existence of a former chapel, which may have been planned but not built, as there is no door at this point. Only the bays of the porch and the flat-chest choir are cross-vaulted. The nave is entered through an original moulded doorway surmounted by a simple entablature. The nave, which now has a ceiling, appears to have had a panelled vault in the past. The windows, all to the south, were probably enlarged in the 18th century when the ceiling was changed.
The church was cleaned and restored in 2012 by the Vals des Tilles Patrimoine association, with the help of the municipality. As part of the restoration, the altarpiece, which used to be placed on the main altar, was moved to the left to allow the choir windows to be reopened. The painting in the centre of the altarpiece is a copy of a work attributed to Raphael's workshop: "La Vierge à la Promenade". During the cleaning of the nave walls, fragments of undated wall paintings were uncovered to the north. Finally, in order to make the church operational, 64 chairs were purchased by subscription by the "Vals des Tilles Patrimoine" association. The church was listed on the Inventaire Supplémentaire des Monuments Historiques on 1 February 1929.
