Barn Island, Singapore
Barn Island (GPS: 1.17039, 103.73454) is the other name for
Pulau Senang, a 81.7-hectare coral island located near the southernmost part of Singapore's international boundary. It was the site of a failed penal settlement that was established in 1960, but closed down after just three years following the rioting by detainees there.
Today Barn Island, along with
Pulau Sudong and
Pulau Pawai, both to its north, is used by the Singapore Armed Forces for live-firing, and is therefore off limits to casual visitors.
