 In the east crypt there is a limestone gothic church monument of the Bishop of Hildesheim and founder of Essen, Altfrid, which dates to around 1300 and was probably built under Abbess Beatrix von Holte.This dating is based on the striking similarity of the tomb to saints' graves at Cologne, especially the grave of St. Irmgard in Cologne Cathedral.The sandstone sculptural group, called the "Entombment of Christ" (Grablegung Christi) in the southern side chapel is from the late Gothic period.
