The current Olympiastadion was originally built for the 1936 Summer Olympics in the southern part of the Reichssportfeld (today Olympiapark Berlin). During World War II, the area suffered little damage. After the war, the British military occupation used the northern part of the Reichssportfeld as its headquarters until 1949. From 1951 to 2005, the Olympischer Platz had a giant antenna transmitting for all the portable radios in Berlin.
