The Changi Airport in Singapore has repeatedly been named the best airport in the world by various global entities. In order to keep up with this reputation, Singapore is currently in the process of executing a mixed-use facility which costs USD 1.7 billion, known as the Jewel. The Jewel which is to comprise of gardens, a waterfall as well as a hotel, is located in a space which was used for parking. The primary attraction of the Jewel is the construction of the Rain Vortex: a 131-foot indoor waterfall which is reputed to be the tallest indoor waterfall in the entire world. The waterfall will be located within a garden known as the Forest Valley and there will be a bridge, known as the Canopy Bridge, which is suspended above ground in order to provide the best view of the Rain Vortex. As of February 2018, around 70% of the Jewel has been completed. For those who are residing in a hotel such as Park Hotel Alexandra, the Rain Vortex is their best chance of seeing a manmade waterfall with ease.
