Dreifaltigkeitskirche, Modern church in Hamm, Germany

The Dreifaltigkeitskirche is a modern church building in Hamburg-Mitte with an elliptical concrete nave and exposed pillars. The tower rises above Horner Weg and shapes the appearance of this neighborhood.

The building was constructed between 1956 and 1957 to replace a church built in 1693 that was completely destroyed during the Operation Gomorrah air raids in July 1943. The reconstruction of the church symbolized Hamburg's recovery after the war.

The name Dreifaltigkeitskirche refers to the Trinity, continuing the dedication of the 1693 predecessor church, consecrated as Ham and Hörner Kirche zur Heiligen Dreyfaltigkeit. The baroque west portal of that earlier building bore the inscription "Deo triuno". Church windows with the coats of arms of donor families survived the war in storage and were reused in the new church.

The church stands on the Horner Weg, a short walk from the U-Bahn stop Hammer Kirche, which takes its name from the building. Its position on the Geest slope makes the tower visible from a distance as a landmark of the district. The Catholic Herz-Jesu-Kirche, rebuilt in 1951/52, stands directly next door.

The tower and nave are built in the shapes of Alpha and Omega, referring to Jesus' self-description as the beginning and the end of the world. The design by Reinhard Riemerschmid was controversial at first. The church has been a listed monument since 2002.
