Construction has begun on the Intercontinental Shimao Shanghai Wonderland, a 19-story hotel outside of Shanghai, China. Almost all those floors will be below ground level. Building them is not as difficult as you'd think at first, as the site is a former rock quarry and most of the underground digging has already been done. There will be an underwater restaurant at the bottom. See more pictures of the current site and future plans at Shanghaist. Link -via Gizmodo
