The Bendlerblock (German pronunciation: [ˈbɛndlɐˌblɔk] ) is a building complex in the Tiergarten district of Berlin, Germany, located on Stauffenbergstraße (formerly named Bendlerstraße). Erected in 1914 as headquarters of several Imperial German Navy (Kaiserliche Marine) offices, it served the Ministry of the Reichswehr after World War I. Significantly enlarged under Nazi rule, it was used by several departments of the Oberkommando der Wehrmacht (OKW) from 1938, especially the Oberkommando des Heeres and the Abwehr intelligence agency.
The building is notable as the headquarters of a resistance band of Wehrmacht officers who staged the 20 July plot against Adolf Hitler in 1944. As the leaders of the conspiracy were summarily shot in the courtyard, the Bendlerblock also includes the Memorial to the German Resistance. Since 1993, the building complex has served as a secondary seat of the German Federal Ministry of Defence.
