This church is one of the purest examples of Romanesque architecture from the Ottonian period. Construction of the basilica, which is based on the form of a cross, was begun in 959. Especially noteworthy is the early use of alternating columns and pillars, later a common Romanesque feature. The octagonal Taufstein (Christening stone), whose religious motifs culminate in the Ascension, dates from 1150. You can also see enclosed in glass Das Heilige Grab , an 11th-century replica of Christ’s tomb in Jerusalem.
