(CBS News) When the cauldron flared with the Olympic flame from Greece Friday night, London officially became the city to host the most Olympic Games.
This is the city's third time as Olympic host, and as Britain's Queen Elizabeth II pointed out Friday, it also is a milestone for her family.
"My great grandfather opened the 1908 Games at White City. My father opened the 1948 Games at Wembley Stadium. And, later this evening, I will take pleasure in declaring open the 2012 London Olympic Games at Stratford in the east of London,'' she said.
The royal family also has other ties to the games. The queen's daughter, Princess Anne, competed as part of the U.K. Equestrian team in 1976. The princess' ex-husband, Mark Phillips, won a gold medal at the 1972 Munich games, also as part of the U.K. Equestrian Team.
This year, their daughter, Zara Phillips, is competing on the five-member U.K. Equestrian Team.
