The elaborate complex consisted of two separate levels, the "Vorbunker" (the upper bunker) or "forward bunker" and the newer Führerbunker one level below. They were both connected together by a stairway set at right angles (they were not spiral). The Führerbunker was about 8.2 meters beneath the garden of the old Reich Chancellery building at Wilhelmstraße 77. This is about 120 meters north of the new Reich Chancellery building, which had the address Voßstraße 6. The Vorbunker was under the large hall behind the old Reich Chancellery. It was connected to the new Reich Chancellery. The Führerbunker was somewhat lower than the Vorbunker and in the west of it. The two bunkers were connected via sets of stairs set at right angles.
