The UK’s largest sculpture, which stands in the Olympic Park, will be lit up during the next two weeks.

Feature lighting has just been added to the ArcelorMittal Orbit, which stands 114.5m tall and was designed by Anish Kapoor and Cecil Balmond.

The sculpture will be lit by 250 colour spot lights that can be individually controlled. The energy efficient LEDs will be positioned in areas including the external spiral staircase, the looping lattices, the canopy and viewing platform areas.

Tests on the lighting will take place over the next fortnight.

Andrew Altman, chief executive of the London Legacy Development Corporation (LLDC), said: “The ArcelorMittal Orbit will become one of London’s most spectacular attractions and a stunning backdrop to the Queen Elizabeth Olympic Park.

“The feature lighting opens a completely new artistic aspect to the work of Anish Kapoor and Cecil Balmond.

“It will create a vivid landmark with dynamic effects that we can use in tandem with different events.”

Ian Louden, head of brand at ArcelorMittal, said: “We’re delighted that the feature lighting, which has been developed together with Anish Kapoor and Cecil Balmond, will extend the ArcelorMittal Orbit experience into the evening hours.”

The ArcelorMittal Orbit will reopen in 2014 when it will be able to accommodate up to 5,000 visitors a day.

A viewing platform will offer people views across London.

Visitors will get to the top of the structure by lift. People can use the lift to get down, or choose to walk the 455 steps of the spiral staircase.

The Orbit will create 50 jobs, 85 per cent of which will be going to people in the Olympic host boroughs - Newham, Tower Hamlets, Hackney, Waltham Forest, Greenwich and Barking and Dagenham.
