The Church of the Redeemer (from the German Erlöserkirche) is an Evangelical (Protestant) church in Bad Homburg, Germany. Finished in 1908, the building is outwardly of a heavy, romanesque revival appearance, while its interior is held in a neo-Byzantine style, with rich marble wall decorations and gold mosaics covering the domed ceiling, leading to the church sometimes being called 'Bad Homburg's Hagia Sophia'.
