Gardens by the Bay, Singapore
One of the world's most impressive indoor gardens is not even located in a temperate climate. Gardens by the Bay in Singapore is a collection of three gardens created on reclaimed land. Much of the greenery is located outdoors, but the venue also has two large conservatories. Because of the year-round warm temperatures, the indoor gardens must often be cooled instead of heated. The Flower Dome Conservatory covers three acres and has foliage from dry and mild climates like the Mediterranean, South Africa and parts of Australia. It is the largest "column-less" conservatory in the world.
The Flower Dome's sister, the Cloud Forest, replicates the cool, moisture-rich ecosystems found between 6,000 and 9,000 feet above sea level in Central America and Southeast Asia. As anyone who has been in sweltering Singapore can attest, a trip to a cool indoor space here can be as welcome as visiting a greenhouse during the middle of winter in colder climes.
