One lonely signpost marks the site where Hitler committed suicide on April 30, 1945. For the last month of his life, Hitler lived roughly eight meters below ground in an air-raid shelter topped by a four-metre-thick, reinforced concrete ceiling. The unremarkable spot can be reached by walking to the end of In den Ministergärten, off Ebertstraße. A parking area surrounded by a pre-fabricated apartment complex covers the location, which was entirely sealed off during the complex's construction in 1988-89. The bunker was once accessed through the Festsaal (ballroom) behind the Reichskanzler-Palais on Wilhelmstraße.
