London Stadium is a multi-purpose outdoor stadium at Queen Elizabeth Olympic Park in the Stratford district of London. It is located in the Lower Lea Valley, 6 miles (10 km) east of central London. The stadium was originally constructed for the 2012 Summer Olympics and 2012 Summer Paralympics, serving as the athletics venue and as the site of their opening and closing ceremonies. Following the Games, it was rebuilt for multi-purpose use and now serves primarily as the home of football club West Ham United, who became anchor tenants from the 2016 season. UK athletics are the other tenants in the stadium and host a round of the World Athletics Diamond League each year, known as the London Grand Prix, sometimes called the London Anniversary Games.
