Today it is a Lutheran women's convent that is maintained by the Hanover monastic chamber (Klosterkammer Hannover).
The monastery was founded in 986 by Count Wale and his wife Odelint according to a decree by King Otto III and is by far the oldest in the former Principality of Lüneburg.
Part of the brick walls and stained glass windows of the chapel are products of the subsequent late Gothic restoration.
The impressive refectory was an endowment from the last German emperor, Kaiser Wilhelm II and his empress.
The introduction of the Lutheran Reformation in the 16th century into all six Lüneburg communities of nuns took several decades.
