This site definitely does match the criteria for a WHS. Should anyone not just read its history, but also compare its architecture and decoration to contemporary churches, you will find its importance as an architectural work of art from the middle ages. Especially the tympanum in the narthex (entry hall) of the church is important to the history of medieval sculpture and can be found in almost any book on art or architecture dealing with this period.

Furthermore, the 19th century restoration/reconstruction by Viollet-le-Duc is almost as much worth calling a heritage 'site' on its own. It reflects the thoughts and views on restoration in France's very first years as a country aware of its valuable historic heritage. Untill the 19th century, all evidence of France's history as a kingdom was considered to be worthless; from about 1800 on, it slowly started to go the other way around. The building up of a new Franch nation after the Revolution was to be nurtured by these reflections on the past, showing France's former excellence in building, craftmanship etc.
