The World’s Tallest Indoor Waterfall

The 40-metre-tall Rain Vortex – the world’s tallest indoor waterfall – is the centrepiece of Singapore’s recently opened Jewel Changi Airport.

The waterfall pours down seven storeys from an oculus in the glass domed roof of the Safdie Architects-designed building at the airport.

Buro Happold engineered the glass and steel bagel-shaped roof, which spans more than 200 metres at its widest point, while Peter Walker and Partners Landscape Architects created the climate-controlled indoor forest.

Singapore experiences frequent thunderstorms, so the Rain Vortex has been designed to funnel rainwater at a rate of 10,000 gallons per minute.

This stream of water will naturally cool the air under the dome, with the captured water will be re-used in the building.
