Holy Cross Church

The church of Kaysersberg, built between 1230 and the 16th century, is dedicated to the Holy Cross. According to tradition, it once housed a relic of the True Cross. A local legend credits its construction to Emperor Frederick Barbarossa, who supposedly financed the work after selling his wife's crown, which was then redeemed by two angels sent by God to help complete the building. Heavily modified in the 15th century, the church retains few original elements, notably its western portal in Romanesque style dating from the 13th century.

Inside, the choir houses a finely crafted wooden altarpiece by Jean Bongart from 1518. In front of the church stands the Emperor Constantine fountain, adding to the site's heritage richness. The Waltrin organ from the 18th century complements the church's musical equipment. An imposing calvary, featuring a Christ over 4.20 meters tall flanked by Mary and John, also draws attention. The stained glass windows, partially rebuilt after World War II destruction, combine 19th-century creations with works from 1952 by glass painter Jean Gaudin.
