St. Peter and Paul's Cathedral, Brandenburg/Havel

St. Catherine's Church, first mentioned in 1217, was endowed with its late Gothic brick during a reconstruction in the 1380s. Restorations were carried out on the exterior in 1864-65 and on the interior in 1842 and 1911-12. The restoration, which was carried out from 1970 to 1992, restored the room's decoration in late Gothic style. The restoration of the roofs, tower and exterior cladding was completed in 2004.

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.

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.
