 The new church was designed by Thomas Germain, known best for his work as a silversmith, and consisted of just a nave and an apse. The entrance of the church was in a circular projection decorated with Ionic pilasters. The apse housed the choir stalls of the canons surrounding the high altar. The nave was decorated with Corinthian pilasters surmounted by an entablature. In the chapel of the Virgin there was a sculpture of the Annunciation by Jean-Baptiste II Lemoyne. The church was also decorated with works by members of the families of painters, Coypel, Restout, and Van Loo. The building enjoyed a good reputation in the middle of the 18th century for its singular plan and rich internal decoration. However, the style of the exterior and portico came under some criticism.
