The St. Marienkirche in Bad Segeberg is one of the most significant Romanesque buildings in Northern Germany. The three-nave brick basilica, whose official documentation dates back to 1199, offers its simple beauty to create the ideal surroundings for the choir and chamber music of the Schleswig-Hostein Musik Festival. The 3-manual organ with 52 stops comes from the Winterhalter organ building workshop and will be available for high-calibre concerts after its consecration in May 2025. Further areas of interest are the magnificent carved altar, which was built in 1515, and the bronze baptismal font from 1447.
