At the 1948 Summer Olympics in London, organizers reminded participants about the true spirit of the Games with a quote from the father of modern Olympics, Baron Pierre de Coubertin, prominently displayed at Wembley Stadium.
This was the first Summer Games held after a 12 year hiatus during World War II. The city constructed no new buildings and no Olympic Village, so athletes stayed in existing accommodations including Royal Air Force camps.
