Potsdamer Platz - Hitler and Germania

Hitler and Germania

Columbushaus was completed and opened in January 1933, the same month that the Nazi dictator Adolf Hitler (1889–1945) came to power. Hitler had big plans for Berlin, to transform it into the Welthauptstadt (World Capital) Germania, to be realised by his architect friend Albert Speer (1905–81). Under these plans the immediate vicinity of Potsdamer Platz would have got off fairly lightly, although the Potsdamer Bahnhof (and the Anhalter Bahnhof a short distance away) would have lost their function. The new North-South Axis, the linchpin of the scheme, would have severed their approach tracks, leaving both termini stranded on the wrong side of it. All trains arriving in Berlin would have run into either of two vast new stations located on the Ringbahn to the north and south of the centre respectively, to be known as Nordbahnhof (North Station) and Südbahnhof (South Station), located at Wedding and Südkreuz. In Speer's plan the former Anhalter Bahnhof was earmarked to become a public swimming pool; the intended fate of the Potsdamer Bahnhof has not been documented.

Meanwhile, the North-South Axis would have cut a giant swathe passing just to the west of Potsdamer Platz, some 5 km long and up to 100 m wide, and lined with Nazi government edifices on a gargantuan scale. The eastern half of the former Millionaires' Quarter, including Stüler's Matthiaskirche, would have been totally eradicated. New U-Bahn and S-Bahn lines were planned to run directly beneath almost the whole length of the axis, and the city's entire underground network reoriented to gravitate towards this new hub (at least one tunnel section, around 220 metres in length, was actually constructed and still exists today, buried some 20 metres beneath the Tiergarten, despite having never seen a train). This was in addition to the S-Bahn North-South Link beneath Potsdamer Platz itself, which went forward to completion, opening in stages in 1939. In the event, a substantial amount of demolition did take place in Potsdamer Straße, between the platz itself and the Landwehrkanal, and this became the location of the one Germania building that actually went forward to a state of virtual completion: architect Theodor Dierksmeier's Haus des Fremdenverkehrs (House of Tourism), basically a giant state-run travel agency. More significantly, its curving eastern facade marked the beginnings of the Runden Platz (Round Platz), a huge circular public space at the point where the North-South Axis and Potsdamer Straße intersected. Additionally, the southern edge of the Tiergarten was to be redefined, with a new road planned to slice through the built-up area immediately to the north of Columbushaus (although Columbushaus itself would remain unscathed); this road would line up with Voßstraße, one block to the north of Leipziger Platz. Here Albert Speer erected Hitler's enormous new Reich Chancellery building, and yet even this was little more than a dry run for an even larger structure some distance further away.

Meanwhile, the Nazi influence was no less evident at Potsdamer Platz than anywhere else in Berlin. As well as Swastika flags and propaganda everywhere, Nazi-affiliated concerns occupied a great many buildings in the area, especially Columbushaus, where they took over most of the upper floors. As if to emphasise their presence, they used the building to advertise their own weekly publication: a huge neon sign on its roof proclaimed DIE BRAUNE POST - N.S. SONNTAGSZEITUNG (The Brown Post - N.S. Sunday Newspaper), the N.S. standing for Nationalsozialist (National Socialist), i.e. Nazi. Probably Potsdamer Platz's most prominent landmark in the mid-1930s, the sign first appears in photographs dated 1935 but was gone again by 1938. On an even darker note, those Nazi concerns included the Gestapo, who set up a secret prison in an upper part of the building, complete with interrogation and torture rooms. Meanwhile, in another part of the building, the Information Office of the Olympic Games Organising Committee was housed. Here much of the planning of the 1936 Berlin Summer Olympic Games took place.
