Architecture in Singapore

Eighteen Supertrees, 25 to 50 metres tall, and two vast glasshouses: the cool Flower Dome and the Cloud Forest with its 35-metre waterfall. The outdoor gardens are free.

The Supertree light-and-music show, nightly at 7:45pm and 8:45pm. Lie back on the grove’s lawns to watch.

Moshe Safdie’s three towers and sky-park. The Spectra light-and-water show runs on the promenade at 8pm and 9pm, plus 10pm on Fridays and Saturdays.

A UNESCO World Heritage Site since 2015, open 5am to midnight and free; only the National Orchid Garden charges entry.

Safdie’s glass doughnut around the 40-metre Rain Vortex, with a five-storey indoor forest and a nightly light show on the falling water.

Vertical gardens that collect rainwater and vent the conservatories; walk the OCBC Skyway between them.
