 Taking advantage of necessary renovations to expand the church enclosure was not unusual.The new parts, presumably built at the order of the abbesses Agana and Hathwig, were an outer crypt, a westwork and a narthex and an external chapel of St John the Baptist.This building can be reconstructed from archaeological finds and did not have a long existence, because a new church was erected, perhaps under the art loving Abbess Mathilde, but maybe only under Abbess Theophanu (r. 1039–1058).
