After the 2012 Olympics a multi-million-pound conversion of the stadium began. 25,000 seats were removed, the floodlights were replaced, the black and white seating design from the Olympics was changed to a white, blue and claret design and a new roof was built to improve acoustics. It is believed to be the largest cantilevered roof in the world.
It is now called London Stadium and hosts the home matches of Premier League football club West Ham United as well as UK Athletics meets and regular rock concerts.
