The ArcelorMittal Orbit is a 114.5-metre (376-foot) sculpture and observation tower in the Queen Elizabeth Olympic Park in Stratford, London. It is Britain's largest piece of public art, and is intended to be a permanent lasting legacy of London's hosting of the 2012 Summer Olympic and Paralympic Games, assisting in the post-Olympics regeneration of the Stratford area. Sited between the Olympic Stadium and the Aquatics Centre, it allows visitors to view the whole Olympic Park from two observation platforms.
