Take a look at these exclusive photos of the construction underway on the iconic Olympic tower, set to become Britain’s largest piece of public art and a visitor attraction for years to come.

Taken by the Olympic Park Legacy Company. these snaps give a sneak peek of the eye-catching ArcelorMittal Orbit, currently at a third of its final height which will see it stand 114m above the Olympic Park.

The tower will eventually be made up of a “continuous looping lattice of tubular steel” - 1,400 tonnes of steel to be exact - set to be finished by early 2012.

Designed by artists Anish Kapoor and Cecil Balmond, the tower will surprisingly only need four men to put it together - a crane driver, two steel erectors and a site foreman.

It promises to give east Londoners and visitors from across the world a stunning look at London’s skyline from viewing points and it is predicted that it will get 1 million visitors in its first year.

It will also generate �10 million a year through ticket sales.

Once the London 2012 Olympics has finished, it will re-open as a visitor attraction by May 2013.
