Kreuzkirche, Gothic Revival church in central Bremerhaven, Germany

The Kreuzkirche is a long rectangular church with a pitched roof and a large round-arched portal, built in 1952 to designs by Fritz Berg and Hans Siegers at Bgm.-Martin-Donandt-Platz. It occupies the site of Bremerhaven's first gasworks and was converted from a former ethnographic museum. A free-standing tower was added in 1961/62, and the interior features leaded glass with biblical scenes by Bremen glass artist Heinz Lilienthal.

This building opened in 1952 after earlier churches in the city were destroyed during World War II. It was created by converting a former ethnographic museum, making it the first post-war church building in Bremerhaven.

The congregation, with 3,300 members in 2022, runs a women's club, senior groups, Bible circles, a choir, a trombone choir and a classical guitar group. Since 2014 it has been involved in the refugee network, and it maintains a kindergarten and an adjacent family centre.

Visitors can enter the church during regular open hours to explore the interior and observe the architectural details. A café operates twice weekly on the premises, offering a comfortable spot to visit and connect with others.

The church stands on ground that once belonged to Bremerhaven's first gasworks. Its leaded glass with biblical scenes was made by Bremen glass artist Heinz Lilienthal, and the crucifix is the work of Georg Grygo. Wide folding doors to the community hall let the worship space be enlarged for larger gatherings.
