The Kaiser-Wilhelm-Gedächtniskirche or Emperor William Memorial Church is one of Berlin's most famous landmarks. The damaged tower is a symbol of Berlin's resolve to rebuild the city after the war and a constant reminder of the destruction of war.Built between 1891 and 1895 by Kaiser Wilhelm II, the church was a symbol of Prussian unity and a mark of honor for his grandfather, Kaiser Wilhem I. The neo-Romanesque structure was designed by the German architect Franz Schwechten. The building was unusually ornate for a protestant church. It was decorated with a large mosaic depicting the history of Prussia.On the night of November 18, 1943 the church burned down after it was hit by an allied bomb; only the broken west tower of the church was still standing. Local opposition saved the structure - which had become known as the 'hollow tooth' - from demolition in the 1950s and in 1961 a new, octagonal church designed by Egon Eiermann was built alongside the existing tower. The church is a reinforced concrete structure with blue-colored glass bricks
