One of Berlin’s most famous landmarks, the Gedächtniskirche (Memorial Church) is a ponderous neo-Romanesque structure from the late 19th century. Built to commemorate the 1871 establishment of the German Empire, the church was blasted by a bomb in World War II, and its ruined shell was preserved as a symbol of the ravages of war. You probably won’t want to spend more than a few minutes inside. The small modern church beside the Gedächtniskirche is an octagonal hall designed by Egon Eierman in 1961. The modern church, with its gorgeous deep-blue stained glass, is a venue for weekend concerts.
