The ArcelorMittal Orbit is a 115-metre-high (377 ft) sculpture and observation tower in the Olympic Park in Stratford, London. It is Britain's largest piece of public art,[3] and is intended to be a permanent lasting legacy of London's hosting of the 2012 Summer Olympics, 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.
Orbit was designed by Anish Kapoor and Cecil Balmond of engineering Group Arup.
