The Église de l′Invention de la Sainte-Croix or, colloquially, Église Sainte-Croix is the mostly medieval parish church of the small town of Kaysersberg, in the Haut-Rhin department of France. The church is situated on the Romanesque Road of Alsace thanks to its ornate sandstone portal from ca. 1230–1235; it is classified as a Monument historique by the French Ministry of Culture since 1932.
