- Through centuries
- Today : the museography
This sacristy built during the XVIIIth century hosts a permanent museography about the history of this site. Some notice boards and tactile models display the architectural evolution of this place.
Many objects discovered during archaeological investigations (such as capitals, choir screen, altar ornament, terra cotta pavement tiles…) let the visitor imagine how richly the church was decorated throughout the Middle Ages.
