Saint John''s Island, previously known as Pulau Sakijang Bendera, is one of the Southern Islands in Singapore. It is located approximately 6.5 km to the south of the main island of Singapore, off the Straits of Singapore. Saint John''s Island formerly housed a quarantine station for cholera cases detected among immigrants in the late 1800s, and starting from 1901, victims of beri-beri were also brought to the island. By 1930, the island gained world recognition as a quarantine centre screening Asian immigrants and pilgrims returning from Mecca. The quarantine station was eventually also used to house victims of other diseases, such as leprosy. When mass immigration was closed in mid 1900s, the island was used to house a penal settlement and a drug rehabilitation centre. The 40.5-hectare hilly island was transformed in 1975 into a tranquil getaway with swimming lagoons, beaches, picnic grounds, trekking routes and soccer fields. The island is also a haven for a host of flora and fauna, and is popular for weekend visits.
