The present-day Romanesque abbey church at the northern foot of the Mönchsberg was erected from about 1130 onwards at the site of a previous Carolingian church building, it was dedicated to Saint Peter in 1147. One of the organs was located atop the rood screen in 1444, a work by Heinrich Traxdorf of Mainz. While the steeple received its onion dome in 1756, the interior was often re-modelled before attaining its currently visible Rococo style between 1760 and 1782 under Abbot Beda Seeauer's direction. The high altar is a work by Martin Johann Schmidt. The St. Mary's Chapel contains the grave of Abbot Johann von Staupitz (d. 1524), who was Martin Luther's superior; they were both Augustinian monks in Germany at the time.
