Early Thursday morning, the Olympic flame was lit in Olympia, Greece, marking the beginning of the Rio 2016 torch relay.

This year’s ceremony took place in front of the Temple of the Goddess Hera, where the torch was lit and began its six-day trek across Greece, before it is handed over to this summer’s Olympic hosts.

The Hellenic (Greek) Olympic Committee announced a total of 450 people will carry the torch in the home of the Olympic Games. The torch will be handed over to Brazil on April 27 at a ceremony in Panathinaiko Stadium, a venue from Athens 1896.

With the Rio 2016 torch relay underway, here’s a look at six cool torch relay legs throughout Olympic history.

Melbourne 1956

Ahead of Melbourne 1956, there was a portion of the torch relay that took the flame to Stockholm, which would host the equestrian events five months before the rest of the Games. All of the torchbearers for this relay carried the flame on horseback. Australian law forced the separation of the equestrian events due to a six-month quarantine period before foreign horses could enter the country.

During the Olympic flame’s journey to Grenoble 1968, a diver swam across of port of Marseilles while holding the flame out of water (yes, out of water). The torches used were made from bronzed steel and had a protective covering for the flame, which helped ensure it stayed lit throughout this unique leg.

Montreal 1976

During Canada’s first time as Olympic hosts, the flame was transmitted to Ottawa from Athens via satellite. Montreal 1976 was also the first time two people lit the Olympic cauldron together, the lucky torchbearers were teenagers Stéphane Préfontaine and Sandra Henderson.

During the 1992 Olympic Winter Games relay, the torch traveled faster than the speed of sound, while flying from Athens to Paris on the Concorde. Albertville 1992 also marked the last time a summer and winter Olympic Games were held in the same year. Barcelona hosted the summer Games, its torch journey included travelling on the frigate Cataluña on the passage between Greece and Spain

For the first time in history, a transfer of the flame took place between two parachute jumpers. The relay was capped with ski jumper Stein Gruben launching himself and the flame into the air before the cauldron was lit by Crown Prince Haakon.

Although the torch had been to space before, the Sochi 2014 relay marked the first time it was taken on a space walk, which first meant a blast off aboard a Soyuz rocket and some time aboard the International Space Station.
