Bailong Elevator

The Bailong Elevator is a glass elevator built onto the side of a huge cliff in the Wulingyuan area of Zhangjiajie, People's Republic of China that is 326m high. It is claimed to be the highest and heaviest outdoor elevator in the world. Construction of the elevator began in October 1999, and it was opened to the public by 2002. The environmental effects of the elevator have been a subject of debate and controversy, as the Wulingyan area was designated a World Heritage Site in 2002. Operations were stopped for 10 months in 2002–2003, reportedly due to safety concerns, not environmental ones
