On the castle-hill, a steep sandstone-rock, approximately 25m over the roofs of the city Quedlinburg, rise the towers of the Romance seminary church St. Servatius. Together with the residential premises of the ladies` convent they form a group of buildings of great significance and architectural charm. The Quedlinburger seminary church, which emerged from a residential chapel of King Heinrich I., was used from 936 until 1803 as a place of worship for the secular ladies convent.
