Friedenskirche Ludwigshafen, Cultural heritage monument in Südliche Innenstadt, Ludwigshafen, Germany.

The Friedenskirche is a church in the southern downtown area of Ludwigshafen featuring traditional German architecture. The building displays stained glass windows and stone craftsmanship typical of churches from this period.

The Friedenskirche was built in 1931/32 as the second Protestant church in Ludwigshafen-Friesenheim, designed by Karl Latteyer and Hans Schneider after they won an architecture competition, and executed by Joseph Hoffmann & Söhne AG. Badly damaged by bombing in 1943/1944, it was to be demolished after the war, but resistance from the congregation led to its reconstruction in 1954/1955 under Ernst Zinsser. It was listed as a monument in 1992.

The church's nickname, "Seelengasometer" (soul gasometer), came from its round, largely closed shape with only narrow high window slits in the massive outer wall. The 1954/55 rebuild kept the circular form but replaced the wall with clear glazed concrete grid blocks, and the Heidelberg artist Harry MacLean made the choir altarpiece as a glass mosaic on the Golgotha theme.

The building is easily accessible by public transportation with several bus and tram lines nearby. Visitors should check the opening times beforehand to ensure the church is open when they visit.

The original 1931/32 church had a diameter of 35 metres and a total height of 54.40 metres to the tip of the cross; locals nicknamed the closed round shell the "Seelengasometer". The rebuilt interior was reduced to 30 metres, while the outer diameter is now 38 metres.
