[2][3] On 20 February 1529, when Strasbourg openly joined the Reformation and suspended the practice of the Mass, the church became Lutheran.
The 1762 pipe organ of the Catholic part was moved to the Church of Saint Maurice in Soultz-les-Bains in 1865.
The Catholic Church contains relics of Brigit of Kildare as well as a number of important works of art classified as Monuments historiques such as the "Passion of Christ", a series of ten Gothic paintings by Heinrich (or Henri) Lutzelmann (1485),[7] the "Scenes from the Life of St Peter" an (incomplete) series of four wooden early Renaissance or late Gothic reliefs made around 1500[8] and a series of four 1504 paintings depicting "Scenes of the Life of Christ after the Resurrection".
[9] The Lutheran part of the church, presently owned and used by a congregation within the Protestant Church of Augsburg Confession of Alsace and Lorraine, also features some notable works of art, among which the wooden Renaissance relief "Holy Family" (1520s) by Hans Wydyz, classified as a Monument historique.
