It took six years from the initial idea for a major new piece of public art to the unveiling of
Sky Mirror on 27 April 2001, and cost . At the time, it was the largest
National Lottery grant to any single artwork. In 2009,
Sky Mirror was installed in Brighton's Pavilion Gardens for the
Brighton Festival. From 28 September 2010,
Sky Mirror and three other Kapoor sculptures were exhibited in
Kensington Gardens, London. The open-air exhibition was titled
Turning the World Upside Down and it ran until 13 March 2011. It was accessible from 6 a.m. until dusk. Kapoor said that Kensington Gardens was "the best site in London for a piece of art, probably in the world". The location of
Sky Mirror was previously occupied by a sculpture by
Henry Moore – a work that was donated by the artist, but had been removed for conservation in 1996. Kapoor's sculptures were guarded round-the-clock at a cost estimated to be £120,000 paid for by the
Royal Parks Agency. ==Other versions==
