Jacques Rival - IFO

The IFO, also known as the Identified Flying Object, is created by Jacques Rival and is situated at the Battle Bridge Place of King's Cross. It was installed in 2011 as part of RELAY, the first King's Cross art programme celebrating the area's heritage and future.

The sized-up "birdcage" is at 9m high and 6m wide with bars more than big enough for people to walk through and play with the swing at the centre. At night, the artwork becomes alight with neon rainbow colours lighting up against its backdrop using LED lights. The structure is made of steel.

On special occasions, the artwork is lifted into the air as it illuminates in the night sky.
