The main altar, in the form of a tomb, is a recreation of an earlier altar in the rocaille or late baroque style, which had been damaged in a fire in 1759 and then ruined during the French Revolution. The altar was recreated in 1809 by the architect Pierre-Valentin Boudhors, who discovered the old central medallion of the original altar and combined it with white and black marble panels. The sculptor Jacques Zimmer added the heads of cherubs made of bronze.
