The interior design of Notre-Dame-des-Victoires, as you can see it nowadays, is the work of Raphaël Giroux and a few other students of Thomas Baillairgé, Jean Baillairgé's grandson, who himself worked on the design of the same building in the past. Completed between 1854 and 1857, this design succeeds several previous sets.
During the second century of the church's construction, in 1888, the chair and the churchwarden's pew dating from 1854 were removed and this section was replaced with painted decoration.
