London's 2012 Paralympics has ended with a fiery finale and official handover to 2016 host, Rio de Janeiro.
The show, described as a "festival of flame" honouring Britain's ancient traditions and festivals, brought 11 days of sport to a close.
UK band Coldplay led the show, which started at 20:30 BST, with a live set reflecting the four seasons.
The event ended what organisers say has been "the greatest Paralympic Games ever".
Unlike the other Games ceremonies, the 4,200 athletes were seated around the main arena, putting them at the heart of the action.
Declaring the 2012 Paralympics closed, International Paralympic Committee president, Sir Philip Craven, said: "These Games have changed us all forever."
China finished top of the Paralympic medals table, with 231 medals - 95 gold. Great Britain cemented third place behind Russia, with a tally of 120, including 34 golds.
As the ceremony drew to a close, Paralympians Ellie Simmonds and Jonnie Peacock helped to put out the Paralympic flame, which was shared out across the stadium symbolising "the eternal nature of the flame living among us all".
Each participating country will take home one of the 200 copper petals that made up the Paralympic cauldron.

"The Paralympians have lifted the cloud of limitation."
He added: "Finally, there are some famous words you can find stamped on the bottom of a product. Words, that when you read them, you know mean high quality, mean skill, mean creativity.
'An absolute triumph'
"We have stamped those words on the Olympic and Paralympic games of London 2012.
"London 2012. Made in Britain."

Mr Cameron, whose disabled son Ivan died in 2009, added: "I think back to Ivan. As every parent, you think about all the things they can't do, but at the Paralympics they are superhuman, you see all the things they can do."
He also said it would give momentum to sports participation and the Paralympics had changed perceptions of disabled sport.
