Hamersleben Abbey

The monastery was founded in 1107/1108 in Osterwieck by Bishop Reinhard. Already in 1112, it was relocated to Hamersleben due to extensive land donations from the noble ladies Thietburg and Mathilde. These donations, which extended into the Altmark, formed the economic basis for the foundation's capacity, evident in the construction of the collegiate church, completed before 1140, and an outstanding scriptorium. From its inception, the monastery held extensive administrative and legal powers as a manorial lordship and achieved considerable independence from external influences in the 12th century. Although it originally existed as a double monastery, the admission of women was prohibited in 1238 by Bishop Ludolf I of Halberstadt. After a period of decline in importance, the foundation was reformed in 1452 and joined the Windesheim Congregation. During this time, debts were reduced, and its possessions were expanded.
