Queen Elizabeth Olympic Park is a sporting complex and public park in Stratford, Hackney Wick, Leyton and Bow, in east London. It was purpose-built for the 2012 Summer Olympics and Paralympics, situated adjacent to the Stratford City development. It contains the Olympic stadium, now known as the London Stadium, and the Olympic swimming pool together with the athletes' Olympic Village and several other Olympic sporting venues and the London Olympics Media Centre. The park is overlooked by the ArcelorMittal Orbit, an observation tower and Britain's largest piece of public art. It was simply called The Olympic Park during the Games but was later renamed to commemorate the Diamond Jubilee of Queen Elizabeth II (though it is not an official Royal Park of London). The park occupies an area straddling four east London boroughs; Newham, Tower Hamlets, Hackney and Waltham Forest. Part of the park reopened in July 2013, while a large majority of the rest (including the Aquatics Centre, Velopark and Orbit observation tower) reopened in April 2014.
