3. Kapoor’s and Balmond’s Orbit was announced as the winner on 31 March 2010 and work started in November 2010. Taller than the Statue of Liberty and Big Ben, twice as high as Nelson’s column in London’s Trafalgar Square, the Orbit is a hybrid, a network of art and structure. Around 560 meters of red tubular steel form the structure and 250 colored spotlights illuminate it at night; the tower has two observation floors, a 455-step spiral staircase, lift and restaurant. 60 per cent of the 2,000 tonnes of steel used in the sculpture was drawn from recycled sources, underlining steel’s status as the world’s most recyclable material.
