Opening date set: Singapore airport officials have announced that the new "Jewel Changi Airport" complex will open to travelers on April 17. Perhaps the most impressive aspect of the project is the Rain Vortex, pictured. At over 130 feet high, it's the world's tallest indoor waterfall.

A central hub: Conceived by world-renowned architect Moshe Safdie as a new "magical garden," Jewel Changi Airport is first and foremost a central hub, connecting three of Changi Airport's current four terminals. Click on for a selection of previously released Jewel design renderings.

Steel-and-glass doughnut: The steel-and-glass donut complex it set to become a destination in itself.

Forest Valley: Jewel's two centerpieces are Forest Valley, through which passengers will be able to hike, and Rain Vortex, a gigantic cascade of water from the roof.

Rain Vortex: The Rain Vortex will be transformed by a light and sound show at night.

Canopy Park: The 14,000-square-meter Canopy Park will include gardens, walking trails, playgrounds and restaurants.

Sky Nets: There will be two different kinds of suspended walking nets -- a 250-meter bouncing net and a 50-meter walking net. These too won't open till later in 2019.

A shopaholic's dream: More than 200 retailers from local and international brands will set up shop in the Jewel.

Al fresco indoor dining: Changi's new leisure complex will have a wide selection of food and drink outlets, some with patios offering views of the waterfall.
