The Notre-Dame Church was erected in the downtown between 1764 and 1785 after the secularization and the transfer of Murbach chapter to Guebwiller. The development plan of the building was entrusted to Beuque, an architect from Besançon, but most of the structural work and the neoclassical decoration (one of the best in Alsace) were carried out by Gabriel Ignace Ritter. Around the square, the canonical neighbourhood gathers five houses for the canons and the abbey castle which now houses a branch of Alsace's IUFM.
