The 115m-high structure was an iconic at the Games and became almost synonymous with the Olympics'; towering above the stadium with its distinctive unravelling knot of blood-red steel, it was designed by Anish Kapoor and Cecil Balmond and was largely funded by Britain's richest man and steel tycoon Lakshmi Mittal, who's surname forms part of the structures title. It is currently Britain's largest piece of public artwork, and acted as an observation tower for spectators during the games.
What Next? The structure will continue to be used as a tourist magnet in a similar way to the London Eye. Spectators can see up to 250 acres of the Olympic Park and London's skyline from its summit, which also includes a dining area for guests. During the Olympic Games the entrance fee was £15 for adults and £7 for children, but it is expected that priced will fall now that the event is over.
