Answer: 1936 Summer Olympics, Berlin
Notes: The tradition of the "Olympic torch relay" was started in the 1936 Summer Olympics, Berlin, the capital city of Germany. The modern tradition of moving the Olympic flame via a relay system from Greece to the Olympic venue began with the Berlin Games in 1936. Months before the Games are held, the Olympic flame is lit on a torch, with the rays of the Sun concentrated by a parabolic reflector, at the site of the Ancient Olympics in Olympia, Greece. The torch is then taken out of Greece, most often to be taken around the country or continent where the Games are held. The Olympic torch is carried by athletes, leaders, celebrities, and ordinary people alike, and at times in unusual conditions, such as being electronically transmitted via satellite for Montreal 1976, submerged underwater without being extinguished for Sydney 2000, or in space and at the North Pole for Sochi 2014. On the final day of the torch relay, the day of the Opening Ceremony, the Flame reaches the main stadium and is used to light a cauldron situated in a prominent part of the venue to signify the beginning of the Games.
