Christo. The “largest indoor sculpture ever made”. Opened on March 16 2013, the inflated “Big Air Package” was designed to occupy a 117-meter-tall former gas tank known as Gasometer Oberhausen in Germany. The 90-meter-high, 50-meter-wide sculpture was made from 20,350 square metres of semi-transparent polyester fabric and 4,500 meters of rope, with a volume of 177,000 cubic metres. This was the first major work after the passing of his wife and artistic partner Jeanne-Claude in 2009
