June 24th, 2010 was a big day for Wimbledon, not only because it saw the end of the stunning match between John Isner and Nicolas Mahut (the score is 6-4 3-6 6-7(7) 7-6(3) 70-68 after a 491-minute decider), but also because Queen Elizabeth II made her first appearance at the tournament in 33 years.
The 84-year-old Queen, wearing a memorable turquoise coat and matching hat, greeted the top seeds and former champions such as Billie Jean King and Martina Navratilova.
Serena Williams fortunately had an opportunity to show off her long-practiced curtsy, but as defending champion didn’t get the honor of playing in front of the queen, who instead watched Briton Andy Murray winning his second round match.
Here's a short video of the queen's arrival:
And another video, where you can see shots from the queen's previous visit in 1977:
