Orignele foto enkel met handtekening Christo in formaat 2.05 x 15.5 cm The Mastaba, a project for Abu Dhabi, was conceived in 1977. It will be the largest contemporary sculpture (in volume) in the world, made from 410,000 multi-colored barrels to form a colorful mosaic, echoing Islamic architecture. The Mastaba will be 150 meters (492 feet) high, 300 meters (984 feet) long at the vertical walls and 225 meters (738 feet) wide at the 60 degree slanted walls. The colors and the positioning of the 55-gallon steel barrels were selected by Christo and Jeanne-Claude in 1979, the year in which the artists visited the United Arab Emirates for the first time.
