Friedenskirche, Protestant church in Mülheim district, Cologne, Germany

The Friedenskirche is a Protestant church at Wallstraße 70–72 in Cologne-Mülheim, built in 1786 by Wilhelm Hellwig. It has a cross-shaped plan crowned by a lantern, and from 1845 to 1848 a tower designed by Cologne Cathedral architect Ernst Friedrich Zwirner was added. Each side of the tower has three tall Neo-Romanesque sound windows.

The building grew from a long history starting in 1610 when Lutherans and Calvinists first received permission to construct a church here. After destruction by Rhine ice floes in 1784, it was rebuilt in 1786 at its present location by architect Wilhelm Hellwig.

The name Friedenskirche, adopted in 1837, commemorates the union of the Lutheran and Reformed congregations ordered by Prussian King Friedrich Wilhelm III within the Old Prussian Union. The smaller of the two church halls was sold, and the remaining church took the name of the peaceful merger. The pulpit was once built into the organ casing.

The Friedenskirche stands at Wallstraße 70–72 in Cologne-Mülheim, set back somewhat from the Rhine. The church interior was redesigned in 1998/99, and since 2018 the new organ has been used for concerts alongside services. Visitors should check locally for opening times and event dates.

The building survived multiple crises, most remarkably its reconstruction after the 1784 ice disaster that nearly destroyed it completely. The decision to rebuild it at the same spot demonstrates the deep attachment of the congregation to this location.
