The interior of this Romanesque church is depicted by columns, cornerstones and, above all, intricately carved pillars in the western gallery inspired by the basilica of Königsluttere. Above the gallery on a level with the high windows, admire the early 13C paintings. The 12C altar is graced with a lovely Baroque altarpiece (1675) that came from the wooden sculpture workshop of the Lessen family of Goslar, as did the pulpit (1698).
