Built in 1911 by the Franciscan order, which also built an adjoining convent (now the Maison des Associations and Baumann Square). Opposite, the Place du Rattachement (in honour of the merger with Mulhouse in 1947), with the Paul Stinzi primary school dating from the 1930s. To the left of the church, opposite the rue des sapeurs pompiers, a monument commemorates the 6 civilians shot in reprisal by the German military on the night of 15 August 1914, during which 65 houses and 6 factories were burnt down in Bourtzwiller.
