The baroque interior of the Lady Chapel (rebuilt by Servandoni in 1729) was designed by Charles de Wailly in 1774, after the chapel was badly damaged by a fire which destroyed the nearby Foire Saint-Germain in 1762. The dome, lit by natural light from hidden windows devised by de Wailly, contains a fresco by François Lemoyne depicting the Assumption of Mary, which dates from 1734, although it has been restored several times since then. De Wailly also designed the pulpit (in the nave), completed in 1788. The oak canopy broadcasts sound very well and it was from here that the parish priest of Saint-Sulpice declared his refusal to accept the Civil Constitution of the Clergy. Revolutionary orators used it later also.
