Singapore Botanic Garden.  Singapore.

"The idea of a national garden in Singapore started in 1822 when Sir Stamford Raffles, the founder of modern Singapore and a keen naturalist, developed the first ‘Botanical and Experimental Garden’ at Fort Canning. It was only in 1859 that the Gardens at its present site was founded and laid out in the English Landscape Movement’s style by an Agri-Horticultural society."  Source: Official Garden website.
