On the roof of the John Peel wing, mirroring the radio mast, is "Breathing", a cone-shaped glass structure reaching into the sky to the same height as the mast. It was sculpted by Jaume Plensa as a memorial to journalists killed in the line of duty. It includes words from a poem by James Fenton and is illuminated day and night. At 10 pm daily, in line with the "BBC News at Ten", a column of light shines into the sky. It was officially unveiled on 16 June 2008 by the UN Secretary General Ban Ki-Moon.
