History+
The Rehna Monastery was founded between 1236 and 1237. Initially, it was a convent of Benedictine nuns. Over the course of its history, the monastery changed its affiliation and was subsequently inhabited by Premonstratensian nuns and finally by Cistercian nuns. The monastery was dedicated to the Virgin Mary and Saint Elisabeth. It developed into an important spiritual center in Mecklenburg, supported by donations and the education of daughters from noble families. In the course of the Reformation, Rehna Monastery was dissolved in 1552.
