The Night Safari is the world's first nocturnal zoo and is one of the most popular tourist attractions in Singapore.
The concept of a nocturnal park in Singapore was suggested in the 1980s by the former executive chairman of the Singapore Zoo, Dr Ong Swee Law. Constructed at a cost of S$63 million, the Night Safari was officially opened on 26 May 1994 and occupies 35 hectares (86 acres) of secondary rainforest adjacent to the Singapore Zooand Upper Seletar Reservoir.
