The interior of Saint-Ignace-de-Loyola Church reflects the monumental nature of the building, which was inaugurated in 1934. The church was designed primarily by E. Henri Talbot. The layout allowed the congregation to see the liturgical celebrations from wherever they were seated. In the 1960s, the architect carried out further alterations to comply with a decree of the Second Vatican Council. This resulted in the stripped-back decor that is still visible today.
