Pulau Senang

Pulau Senang is an coral island in the Republic of Singapore, located about off the southern coast of Singapore Island. Along with Pulau Pawai to the north-west and Pulau Sudong, further north from Pulau Pawai, it is used as a military training area for live-fire exercises carried out by the Singapore Armed Forces (SAF).

Pulau Senang is best known in the history of Singapore as the location of a former experimental offshore penal settlement. It failed after only three years, following an infamous riot against the small unit of prison authorities (no more than 10) which broke out in 1963, resulting in the death of four officers, including the prison chief.
