The Führerbunker (German pronunciation: [ˈfyːʁɐˌbʊŋkɐ] ) was an air raid shelter located near the Reich Chancellery in Berlin, Germany. It was part of a subterranean bunker complex constructed in two phases in 1936 and 1944. It was the last of the Führer Headquarters (Führerhauptquartiere) used by Adolf Hitler during World War II.
Hitler took up residence in the Führerbunker on 16 January 1945, and it became the centre of the Nazi regime until the last week of World War II in Europe. Hitler married Eva Braun there on 29 April 1945, less than 40 hours before they committed suicide.
After the war, both the old and new Chancellery buildings were levelled by the Soviet Red Army. The underground complex remained largely undisturbed until 1988–89, despite some attempts at demolition. The excavated sections of the old bunker complex were mostly destroyed during reconstruction of that area of Berlin. The site remained unmarked until 2006, when a small plaque was installed with a schematic diagram. Some corridors of the bunker still exist, but are sealed off from the public.
The Reich Chancellery bunker was initially constructed as a temporary air-raid shelter for Hitler, who actually spent very little time in the capital during most of the war. Increased bombing of Berlin led to expansion of the complex as an improvised permanent shelter. The elaborate complex consisted of two separate shelters, the Vorbunker ("forward bunker"; the upper bunker), completed in 1936, and the Führerbunker, located 2.5 metres (8 ft 2 in) lower than the Vorbunker and to the west-southwest, completed in 1944. They were connected by a stairway set at right angles and could be closed off from each other by a bulkhead and steel door. The Vorbunker was located 1.5 m (4 ft 11 in) beneath the cellar of a large reception hall behind the old Reich Chancellery at Wilhelmstrasse 77. The Führerbunker was located about 8.5 m (28 ft) beneath the garden of the old Reich Chancellery, 120 m (390 ft) north of the new Reich Chancellery building at Voßstraße 6. Besides being deeper under ground, the Führerbunker had significantly more reinforcement. Its roof was made of concrete almost 3 m (9 ft 10 in) thick. About 30 small rooms were protected by approximately 4 m (13 ft 1 in) of concrete; exits led into the main buildings, as well as an emergency exit up to the garden. The Führerbunker development was built by the Hochtief company as part of an extensive programme of subterranean construction in Berlin begun in 1940. The construction cost for the Führerbunker totaled 1,349,899.29 Reichsmarks.
Hitler's accommodations were in this newer, lower section, and by February 1945 it had been decorated with high-quality furniture taken from the Chancellery, along with several framed oil paintings. After descending the stairs into the lower section and passing through the steel door, there was a long corridor with a series of rooms on each side. On the right side were a series of rooms which included generator/ventilation rooms and the telephone switchboard. On the left side was Eva Braun's bedroom/sitting room (also known as Hitler's private guest room), and an antechamber (also known as Hitler's sitting room), which led into Hitler's study/office. On the wall hung a large portrait of Frederick the Great, one of Hitler's heroes. A door led into Hitler's modestly furnished bedroom. Next to it was the conference/map room (also known as the briefing/situation room) which had a door that led out into the waiting room/anteroom.
The bunker complex was self-contained. However, as the Führerbunker was below the water table, conditions were unpleasantly damp, with pumps running continuously to remove groundwater. A diesel generator provided electricity, and well water was pumped in as the water supply. Communications systems included a telex, a telephone switchboard, and an army radio set with an outdoor antenna. As conditions deteriorated at the end of the war, Hitler received much of his war news from BBC radio broadcasts and via courier.
Hitler moved into the Führerbunker on 16 January 1945. His senior staff, including Martin Bormann and Joseph Goebbels, as well as Braun, joined them in April, while Magda Goebbels and their six children took residence in the upper Vorbunker. Two or three dozen support, medical, and administrative staff were also sheltered there. These included Hitler's secretaries (including Traudl Junge), a nurse named Erna Flegel, and Sergeant Rochus Misch, who was both bodyguard and telephone switchboard operator. Initially, Hitler continued to use the undamaged wing of the Reich Chancellery, where he held afternoon military conferences in his large study. Afterwards, he would have tea with his secretaries before returning to the bunker complex for the night. After several weeks of this routine, Hitler seldom left the bunker except for short strolls in the chancellery garden with his dog Blondi. The bunker was crowded, the atmosphere was oppressive, and air raids occurred daily. Hitler mostly stayed on the lower level, where it was quieter and he could sleep. Conferences took place for much of the night, often until 05:00.
On 16 April, the Red Army started the Battle of Berlin, and they started to encircle the city by 19 April. Hitler made his last trip to the surface on 20 April, his 56th birthday, going to the ruined garden of the Reich Chancellery where he awarded the Iron Cross to boy soldiers of the Hitler Youth. That afternoon, Berlin was bombarded by Soviet artillery for the first time.
Hitler was in denial about the dire situation and placed his hopes on the units commanded by Waffen-SS General Felix Steiner, the Armeeabteilung Steiner ("Army Detachment Steiner"). On 21 April, Hitler ordered Steiner to attack the northern flank of the encircling Soviet salient and ordered the German Ninth Army, south-east of Berlin, to attack northward in a pincer attack. That evening, Red Army tanks reached the outskirts of Berlin. Hitler was told at his afternoon situation conference on 22 April that Steiner's forces had not moved, and he fell into a tearful rage when he realised that the attack was not going to be carried out. He openly declared for the first time the war was lost—and he blamed his generals. Hitler announced that he would stay in Berlin until the end and then shoot himself.
On 23 April, Hitler appointed General of the Artillery Helmuth Weidling, commander of the LVI Panzer Corps, as the commander of the Berlin Defense Area, replacing Lieutenant Colonel (Oberstleutnant) Ernst Kaether. The Red Army had consolidated their investment of Berlin by 25 April, despite the commands being issued from the Führerbunker. There was no prospect that the German defence could do anything but delay the city's capture. Hitler summoned Field Marshal Robert Ritter von Greim from Munich to Berlin to take over command of the Luftwaffe from Hermann Göring, and he arrived on 26 April along with the test pilot Hanna Reitsch.
On 28 April, Hitler learned that Reichsführer-SS Heinrich Himmler was trying to discuss surrender terms with the Western Allies through Count Folke Bernadotte, and Hitler considered this treason. Himmler's SS representative in Berlin, Hermann Fegelein, was shot after being court-martialed for desertion, and Hitler ordered Himmler's arrest. On the same day, General Hans Krebs made his last telephone call from the Führerbunker to Field Marshal Wilhelm Keitel, Chief of German Armed Forces High Command (OKW) in Fürstenberg. Krebs told him that all would be lost if relief did not arrive within 48 hours. Keitel promised to exert the utmost pressure on Generals Walther Wenck, commander of the Twelfth Army, and Theodor Busse, commander of the Ninth Army. Meanwhile, Bormann wired to German Admiral Karl Dönitz: "Reich Chancellery a heap of rubble." He said that the foreign press was reporting fresh acts of treason and "that without exception Schörner, Wenck and the others must give evidence of their loyalty by the quickest relief of the Führer".
