Video: London Olympics 2012: Anish Kapoor's Orbit rises from the ground With its circular staircase and lift leading to a two-deck viewing platform, the 374-foot sculpture, designed by Anish Kapoor and Cecil Balmond, will provide visitors with views over the Olympic Park and across east London to the City and beyond. Visitors will even be able to catch a glimpse of the action in the 80,000-seat Olympic Stadium below, although a family ticket for entry to the tower could cost as much as £60. The ArcelorMittal Orbit, to give the tower its full name, will be the UK's tallest sculpture and is expected to attract a million visitors a year. Boris Johnson, the Mayor of London, persuaded Lakshmi Mittal, the steel magnate and Britain's richest man, to supply the 1,400 tons of metal for the tower, at a cost of £19.6 million, with the remaining £3.1 million put up by government.
