“The Olympiastadion is a sports stadium at Olympiapark Berlin in Berlin, Germany. It was originally built by Werner March for the 1936 Summer Olympics.
When the Nazis came to power in Germany (1933), they decided to use the Olympic Games in 1936 for propaganda purposes. With these plans in mind, Adolf Hitler ordered the construction of a great sports complex in Grunewald named the “Reichssportfeld” with a totally new Olympiastadion.
The capacity of the Olympiastadion reached 110,000 spectators. It also possessed a special stand for Adolf Hitler and his political associates. At its end, aligned with the symmetrically-designed layout of the buildings of the Olympischer Platz and toward the Maifeld, was the Marathon Gate with a big receptacle for the Olympic Flame.” - https://en.wikipedia.org/wiki/Olympiastadion_(Berlin)
