Thousands of people have flocked to the Olympic Park to rekindle the spirit of London 2012, which started exactly a year ago.
The Open East Festival is celebrating the anniversary of the Games and marking the opening of the northern part of the park to the public, which is now called the Queen Elizabeth Olympic Park.
More than 50,000 people are expected to visit the event over the weekend before the park will be free for the public to explore from Monday at 2pm.
The festival's centrepiece is a life-size bouncy castle replica of Stonehenge by the Turner Prize-winning artist Jeremy Deller while art organisation the Barbican is hosting the main music stage, a giant blue circus tent.
Visitors have been browsing artwork by local East End artists including Bob & Roberta Smith, Gavin Turk and Pure Evil as well as tucking into food from around the world.
Tickets for the festival cost £9.50 for adults, £6 for children over five and free for under five-year-olds.
