This is the Gothic Church from the old Benedictine abbey of St-Père-en-Vallée. The clock tower door dates from a pre-Roman building. In the arches to the right of the chancel the oldest stained-glass windows depict in hieratic forms people from the Old Testament. Vibrating with colour the stained-glass windows of the hemicycle of the chancel were installed around 1300. Finally installed (around 1305 - 1315) were the windows of the nave alternating important people with medallions.
