Numerous castles are found in the German states of Berlin and Brandenburg. These buildings, some of which have a history of over 1000 years, were the setting of historical events, domains of famous personalities and are still imposing buildings to this day.
This list encompasses castles described in German as Castle (castle), Festung (fort/fortress), Palace (manor house) and Palace/Palast (palace). Many German castles after the Middle Ages were mainly built as royal or ducal palaces rather than as a fortified building.

Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby.

The Protestant Church of the Redeemer is located to the south of the village of Sacrow, which since 1939 has been incorporated to Potsdam, the capital of the German Bundesland of Brandenburg. It is famous for its Italian Romanesque Revival architecture with a separate campanile and for its scenic location. It was built in 1844. The design was based on drawings by King Frederick William IV of Prussia, called the Romantic on the Throne. The building was realized by Ludwig Persius, the king's favorite architect. In 1992, the church along with the park and Sacrow Manor was added by UNESCO to the World Heritage Site "Palaces and Parks of Potsdam and Berlin" for its architecture and cohesion with the surrounding park.
