Erlöserkirche, Protestant church in Bad Honnef, Germany

The Erlöserkirche is a Neo-Romanesque church built in 1899/1900 to a design by Ludwig Hofmann, with details by the Honnef architect Ottomar Stein. Its square tower carries a steep red-tiled pyramidal roof with a forward-facing gable, two open arched belfries and round clock faces with Roman numerals; white walls are framed by beige stone quoins. Inside, a barrel-vaulted nave has a grey trussed timber roof, blue pews and a gallery beneath the organ.

After the Protestant parish was founded on 1 July 1895, a church and parsonage were approved in 1896. Ludwig Hofmann designed the Romanesque Revival building, with details by Ottomar Stein; the foundation stone was laid on 29 May 1899 and the church was consecrated on 2 December 1900. Kaiserin Auguste Viktoria took over patronage, and Wilhelm II replaced Hofmann's tall spire with a bishop's mitre roof.

The name Erlöserkirche (Church of the Redeemer) has been used since 1997. The congregation was founded on 1 July 1895, and the church belongs to the Kirchenkreis An Sieg und Rhein of the Evangelical Church in the Rhineland. The glass mosaic above the main entrance was donated by Kaiserin Auguste Viktoria and Wilhelm II, and Queen Sophia of Sweden and Norway gave a choir window.

The Erlöserkirche stands at Luisenstraße 13, on the western edge of Bad Honnef's town centre, a short walk from the pedestrian zone. The entrance was relocated during the post-war restoration, so the door does not sit where the 1900 plans placed it. The church is a listed monument and is used for services of the An Sieg und Rhein church district.

The church appears as a filming location in Rabiye Kurnaz gegen George W. Bush (2022), a feature film about the German-born Rabiye Kurnaz and her legal fight over the detention of her son at Guantanamo. The nave and gallery served as a courtroom set, so the interior seen on screen is the same vaulted hall visitors enter today.
