What is being claimed as the world’s tallest indoor waterfall and a forest feature in a new £951 million tourist attraction being added to Singapore Changi airport.

Described as a multi-dimensional tourist destination, Jewel is due to open on April 17.

The 137,000 square metre attraction will house aviation, travel-related and lifestyle facilities as well as 280 shops and play attractions.

Ten storeys high under a glass and steel facade, Jewel will be directly connected to terminals 1, 2 and 3 as the Asian hub.

The development will feature a four-storey forest valley containing thousands of trees and plants.

The 40-metre high Rain Vortex waterfall will be surrounded by stores and restaurants and 130-room Yotel hotel.

Three attractions – Sky Nets, Canopy Mazes and Discovery Slides – are planned for a second phase opening in mid-2019.

Changi Airport Group corporate and marketing communications senior vice president Ivan Tan said: “Jewel is set to be a unique destination, like no other. It offers a mix of lush greenery, a scenic waterfall, incredible retail offerings and family play attractions that together make for an unrivalled experience.

“We are excited to bring a new dimension to the travel and leisure experience of our visitors,”
