The oldest people buried here are a husband and wife, Abelard (1079-1142) and Heloise (1101-1164). Many graves have been added since that time. The most recent I saw was in 2011, but most are very old. Many are moss covered or strewn with cobwebs; some have sunken over time.
Lots of the family plots are marked by crypts where the bereaved can come to pray. The smell of incense and flickering of candles can be found at several graves. As sunlight shines through the stained glass that appears in the back and sides of many of the crypts, color can be seen through designs cut into the doors in their fronts.
