The Protestant Church of the Redeemer (German: Heilandskirche, Latin: S. Ecclesiae sanctissimi Salvatoris in portu sacro) 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 (bell tower) 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.
