Christo presents The Mastaba 

The renowned Bulgarian-born artist Christo revealed his first major outdoor project in the UK. The Mastaba is a pyramidal sculpture made of more than 7,000 stacked barrels floating on the Serpentine lake in London's Hyde Park from June 18 to September 23. It was inspired by the trapeze-formed burial tombs typical of ancient Egypt.The opening of The Mastaba coincides with the artist's retrospective in the adjacent Serpentine Galleries. As Christo explained, the exhibition explores the use of oil barrels in his works from 1958 to today and provides important context for the London piece.Christo is world-famous for his large-scale installations that transform their surrounding, like "The Gates" in New York's Central Park or, most recently, "The Floating Piers" on Lake Iseo in Italy.
