malfunction, a fourth arm meant to be lit by Catriona Le May Doan did not rise), Gretzky was escorted outside to light a second, public cauldron at Jack Poole Plaza. During the 2012 Summer Olympics in London, the cauldron located inside the Olympic Stadium was not visible from outside of the stadium. The image of the lit cauldron was projected on the stadium's rooftop screens during the first week of competition, and live footage was available to broadcasters. The notion of a public cauldron displayed outside of the ceremonies venue, and lit following the opening ceremony, was adopted by several subsequent Olympics since Vancouver, such as 2016 at the Candelária Church plaza, and 2020 in Ariake, Tokyo. The 2022 Winter Olympics had three public cauldrons located, the main outside of the Beijing National Stadium,and the another one at the Yanqing District, and a one at Zhangjiakou — reflecting the three main zones of the Games' venues. Doves Beginning at the post-World War I 1920 Summer Olympics, the lighting of the Olympic flame was followed by the release of doves, symbolizing peace. (Experienced athletes brought newspapers to cover themselves because of the birds' droppings.) The release was discontinued after several doves perched themselves at the cauldron's rim and were burned alive by the Olympic flame during the opening ceremony of the 1988 Summer Olympics in Seoul. It was later replaced with a symbolic release of doves after the flame has been lit. In the 2000 ceremony, a dove image was projected on an enormous white cloth held by the athletes on the stadium floor. In 2004, an LED screen was used. In 2006, acrobats formed the shape of a dove. The 2008 ceremony had yellow fireworks and the people made birds with hands representing doves. In 2010, dove figures were projected on the stage floor. The 2012 ceremony had bicyclists with dove-wings, lit by LEDs. In the 2014 ceremony several dancers, holding strands of blue LED lights, danced on the shape of a dove projected on the stadium floor. In the 2016 ceremony, children with dove shaped kites were seen running with the first Olympic Laurel winner, Kipchoge Keino. In the 2018 ceremony, a dove shape was made by the performers by passing candlelight and was accompanied by the song "Imagine" by John Lennon. In the 2020 ceremony, the doves were made of paper and were flown by the performers. Medal
