A Romanesque basilica was built during the 11th century above the grave site of the Franconian martyrs Kilian, Kolonat and Totnan.
An impressive Baroque façade and a cupola were added from 1710-1716. The rich interior houses treasures such as a Madonna and the tombstone of the abbot Trithemius by Riemenschneider.
Parts of an old cloister from the 12th-century Staufer era, including the grave site of medieval poet and minstrel singer Walther von der Vogelweide, are situated behind Neumünster Church in the Lusam Garden.
