What was the official name of the bunker where Joseph Goebbels's wife and children died in 1945?
Vorbunker The Vorbunker (upper bunker or forward bunker) was an underground concrete structure originally intended to be a temporary air-raid shelter for Adolf Hitler and his guards and servants. It was located behind the large reception hall that was added onto the old Reich Chancellery, in Berlin, Germany, in 1936. The bunker was officially called the "Reich Chancellery Air-Raid Shelter" until 1943, when the complex was expanded with the addition of the "Führerbunker", located one level below. On 16 January 1945, Hitler moved into the "Führerbunker". He was joined by his senior staff, including Martin Bormann. Later, Eva Braun and Joseph Goebbels moved into the "Führerbunker" while Magda Goebbels and their six children took residence in the upper "Vorbunker". The Goebbels family lived in the "Vorbunker" until their deaths on 1 May 1945.
Schwerbelastungskörper The Schwerbelastungskörper (German: "heavy load-bearing body"; a.k.a. Großbelastungskörper - GBK) is a hefty concrete cylinder in Berlin, Germany located at the intersection of Dudenstraße, General-Pape-Straße, and Loewenhardtdamm in the northwestern part of the borough of Tempelhof. It was erected in 1941–1942 by Hitler's chief architect Albert Speer to determine the feasibility of constructing large buildings on the area's marshy, sandy ground, specifically a massive triumphal arch on a nearby plot. The arch, which would be in the style of the Nazi architectural movement, was to be about three times as large as the "Arc de Triomphe" in Paris and was one component of a plan to redesign the center of Berlin as an imposing, monumental capital reflecting the spirit of the Third Reich as envisioned by Hitler.
