The most unusual feature of the church is the jubé or rood screen, created in about 1530, the only existing example in Paris. It is an elaborate sculptural screen which separates the nave from the choir. The screen was used as a platform to read the scripture to the ordinary parishioners. They were very common during the Middle Ages, but were largely abolished in the 17th and 18th centuries under a decree of the Council of Trent (1545–1563) which aimed at making the ceremonies in the choir more visible to the ordinary parishioners in the nave.
