This former monastery church, completed between 1220 and 1225, is an interesting example of the transition between the Romanesque style (western portal and semi-circular bays) and the Gothic style (buttresses with projecting arches, ogives resting on a ring of columns, hooked capitals, etc.). This new style, which is probably not directly related to the arrival of the Chartres workshop at the construction site of the southern crosspiece of Strasbourg cathedral, is more a reflection of Burgundian influences moving towards Lorraine. Of the conventual buildings belonging to the community of Augustinian canons, only the refectory, a watchtower and the former prior’s house are still visible.
