St. Catherine's Church, Brandenburg/Havel

The Monastery of St. Paul was founded in the 13th century but was built in several phases, the last of which was completed in 1497 with the construction of the chapel and library. After the Reformation, the monastery came into the possession of the city, which operated a hospital and a benefactor's house there. The church served as a Protestant parish church from 1560, and the monastery and church burned down during the Second World War. Since 2008, St. Paul's Monastery has been open to the public again. It houses the State Archaeological Museum. The monastery church serves as a venue for events.

St. Peter and Paul's Cathedral was founded in 1165 as a Romanesque cathedral. Around 1295, its extension in Flamboyant Gothic style began, which allowed the cathedral to be transformed into a hall church. It was only with the completion of the vaulting of the nave and the east building that the Gothic conversion was completed from 1426 to around 1460.

Lehnin Abbey, was in operation as a Cistercian abbey from 1180 to 1542. Of great cultural influence in the Middle Ages, its restoration in the years 1871-1877 was a milestone in architectural restoration. Since 1911, it has housed the Louise-Henriette Foundation.
