Tate unveils 'scribble in space'

The sculpture is made from aluminium box tubing, just 76mm wide

An 80-metre-long sculpture made up of 26 huge connected triangles has been unveiled at Tate Britain in London.

Described by the gallery as a 'scribble in space', Cold Corners by Eva Rothschild was commissioned specially for the Duveen Galleries.

The metal sculpture, which weighs 1.8 tonnes (1,800kg), stretches throughout the entire space of the Duveens, reaching up to 12m as it loops upwards.

It is on display at the Tate from 30 June until 29 November.

Stephen Deuchar, director of Tate Britain, said the structure looked like it was standing "as if by magic".

'Alternative experience'

He said it was "almost like a lightning strike in the middle of Tate Britain - it is really thrilling".

Rothschild said she wanted to produce something that would "offer an alternative experience of these stately galleries".

The Irish-born 37-year-old's previous works have also played on illusion and perception.

Her previous sculptures include Jokes (2007), a precariously stacked cascade of interlinked cubes, and Plain Gold Ring (2008), a gold ring standing on what appear to be vertical gold ribbons.

The Duveens commission, which was launched in 2000, sets out to highlight contemporary sculpture.

Mark Wallinger's 2007 work was based on Iraq War protestor Brian Haw's demonstration in Parliament Square.

Last year's installation by Martin Creed centred on an athlete running through the galleries every 30 seconds.
