The internationally – and often controversial - acclaimed artist Christo has unveiled the “largest indoor sculpture ever made”. Prepared to debut in a public exhibition starting March 16, the inflated “Big Air Package” has been designed to occupy a 117-meter-tall former gas tank known as Gasometer Oberhausen in Germany. The 90-meter-high, 50-meter-wide sculpture is made from 20,350 square meters of semitransparent polyester fabric and 4,500 meters of rope, with a total weight of 5.3 tons and a volume of 177,000 cubic meters.
Salt, an essential element for all animal life, is abundant here on Earth, but it still requires extraction from stone deposits or salty waters. The process of mining that salt can produce beautiful landscapes, including deep, stable caverns, multicolored pools of water, and geometric carvings. Some of these locations have even become tourist destinations, serving as concert halls, museums, and health spas touting the benefits of halotherapy. Collected here are images of salt mines across the world, above and below ground.
