1972 Summer Olympics could be worthwhile. For this, however, a new and modern stadium had to be built for the city. Planning The three square kilometer and largely undeveloped Oberwiesenfeld was selected as the centerpiece of the Olympic Games. Due to the proximity to the city center, Munich was able to promote the games with the slogan "Olympia of the short ways", which contributed to the decision-making process. Since the Oberwiesenfeld had served as a parade ground of the Bavarian cavalry regiment and later mainly military purposes, it was – except for armaments works – free of buildings. From 1931 to 1939 the Munich Airport was located on the Oberwiesenfeld. After the World War II, the debris rubble of the bombing of the city was piled up, from which the Olympic Mountain emerged. This was intentionally created in an oval shape, so that it could be used as a tribune foundation for a stadium. In 1964, Munich opened an architectural competition for the planning of a large stadium, which was won by the offices of Henschker from Brunswick and Deiss from Munich. Their stadium design was integrated into an overall concept. In the planning of 1965, the stadium was planned to hold around 100,000 spectators, although later the capacity was reduced for the purpose of reusability. The plans were integrated into an overall concept, with the addition of a multi-purpose arena and a swimming pool on a large, concrete surface. Under the concrete slabs, supply systems and parking lots were to be built. On 26 April 1966, the IOC announced that Munich had prevailed against the other candidates Detroit, Madrid and Montreal. Thus the stadium construction was decided. The original plans of the Olympic Park and the stadium were criticized because of a lack of unity in the urban planning. In addition, the Association of German Architects suggested to avoid any monumentality at the sports facilities because of the Nazi past. The plans were finally rejected. In February 1967, an architectural competition was again advertised, in which by the deadline of 3 July 1967 a total of 104 drafts were submitted, one of which came from the architectural firm Behnisch & Partner. The architect Günter Behnisch and his employee Fritz Auer planned to build the stadium, the Olympic Hall and the swimming pool closely adjacent to each other west of the Olympic Tower, for which the base already existed.
