Friedenskirche, Lutheran church building in St. Pauli district, Germany.

The Friedenskirche is a neo-Romanesque brick church built from 1893 to 1895 to a design by Johannes Otzen. It stands on a five-sided plot bounded by Otzenstraße and Am Brunnenhof, and its walls and tower are visible from the surrounding streets.

The Friedenskirche was built from 1893 to 1895 to plans by Johannes Otzen in the neo-Romanesque style, as a brick church for what was then the independent city of Altona. The area around it only passed to St. Pauli under the Greater Hamburg Act of 1937. Bombing in 1943 heavily damaged the building, and it was rebuilt in altered form by 1955.

The Friedenskirche is one of three church buildings of the Protestant-Lutheran parish Altona-Ost, alongside St. Johannis and the Kirche der Stille. The parish name points to the district's history: until the Greater Hamburg Act of 1937 the area around the church belonged to the independent city of Altona, and only afterwards was it assigned to St. Pauli.

The church sits in the middle of Hamburg-St. Pauli and is easy to reach on foot because it stands right on the street corner at Otzenstraße 19. Visitors should note that this is an active place of worship, so it is best to check opening times before visiting.

The church's first organ came from the Dinse brothers' workshop; when the building was rebuilt by 1955, an instrument from E.F. Walcker & Cie. took its place. The 1943 bombing raids had left the church heavily damaged, so the organ change belongs to the same postwar reconstruction as the walls around it.
