An old parish church (now disused) built in the eleventh and twelfth century in the valley of the Mue outside of the present village of Thaon. It is a fine example of the Romanesque architecture of Normandy . Listed as an historical monument by the list of 1840 (at which point it was closed as a church). First mentioned in a charter, 1147. Between 1896 and 1901, a major restoration campaign was designed by architect Leon Benouville. In its current state, the church consists of a two-storey tower, the only part still standing from a first Romanesque building erected during the second half of the eleventh century, a rectangular choir of two bays, and a nave with five bays built ca. 1130. The nave originally had two aisles, now gone.
