Kloster St. Anna

The history of St. Anna Monastery begins in 1158, when it first existed as a monastery. It was dissolved in 1808 during secularization. A new foundation took place in October 1860 by Abbess Mater Franziska Wiest and other sisters of the Poor Clares order from Regensburg. The neo-Gothic monastery complex was built in 1858/59 south of a Gothic pilgrimage church. In 1898, the institution gained its independence. Due to numerous new entries, the complex was expanded into a four-wing structure in 1891 and received a stepped gable and two towers with spires. The St. Anna monastery church was also extended. Another renovation took place between 1965 and 1966. In 1970, the Poor Clares order was affiliated with the Franciscan order, and the community has since been known as the Franciscan Sisters of St. Anna Poor Clare Monastery, Riedenburg. The monastery church, originally a 14th-century pilgrimage church, was extended in 1735 and 1891 and received its current neo-Gothic tower.

St. Anna Monastery is located in the town of Kelheim in the state of Bavaria, Germany.

The monastery complex is now a listed building in Bavaria. The monastic community consists of eight nuns. Since 1860, a school has been affiliated with the monastery, which has developed into the St. Anna Girls' Realschule. In the 2024/25 school year, 441 students attended the six-year Realschule, taught by 31 teachers, including one monastic teacher. Since 2005, the school has been part of the School Foundation of the Diocese of Regensburg.
