With its coloured lights and dancing fountains, Granary Square in King's Cross looks pretty snazzy all year round. But now it's been given an extra-special festive touch in the form of a 17-foot-tall Christmas tree, decorated with 1,200 lights and encased in what looks like a block of ice.
The ice is actually cast resin – almost of a quarter of a ton's worth – and the tree is in fact an artwork by sculptor Alex Chinneck. If you've seen the 35-metre-tall upside-down pylon on the Greenwich Peninsula, or the section of the Covent Garden piazza that seemed to be hovering in mid-air last year, then you'll know his work – big, bold, slightly daft public works that play games with everyday objects and make passers-by stop and scratch their heads for a few seconds.
The work has been given a curious title: 'Fighting Fire With Ice Cream'. Maybe Chinneck had been at the eggnog before coming up with this one.
