A spiralling sculpture designed by Turner Prize-winning artist Anish Kapoor has been chosen as the monument to mark the London 2012 Olympic Games.

The 115m tall piece, named the ArcelorMittal Orbit, will be placed in the Olympic Park and will be 22m higher than New York's Statue of Liberty.

The £19.1m design incorporates the five Olympic rings and will offer visitors panoramic views of London.

London Mayor Boris Johnson revealed plans for the tower on Wednesday.

"I am deeply honoured to be invited to undertake this challenging commission," Kapoor said.

"I am particularly attracted to it because of the opportunity to involve members of the public in a particularly close and personal way. It is the commission of a lifetime."

The artist will work with leading structural designer, Cecil Balmond of engineering firm Arup.
