Several works of art were commissioned by the BBC for the refurbishment of Broadcasting House, at an overall cost of more than £4 million. Among these is "World", a pavement artwork by the Canadian-born architect and artist Mark Pimlott. According to the BBC, the work "reflects the global dimension of the BBC’s broadcasting and consists of over 750 stone flags inscribed with place names from around the world, as well as those from history, mythology and fantasy. The artwork is enhanced by elegant steel lines of longitude and latitude, a subtle scheme of small embedded lights and some audio installation linked to key output from the World Service."
