It is the largest prison in the country, covering an area of about 50 ha (120 acres), and the oldest still in operation since the closure of Outram Prison in 1963. Opened in 1936 by the British colonial government to replace Outram Prison, the complex was constructed with the intention of housing a large number of prisoners due to the rapid growth of the colony and need for a larger penal facility to alleviate prison overcrowding. \nFollowing the fall of Singapore and subsequent Japanese occupation in 1942, Changi Prison was used by the occupational authorities as a prisoner-of-war camp for Allied prisoners of war (POWs). Many of these prisoners were subjected to brutal treatment and forced labour, and a significant number died from malnutrition, disease, and mistreatment.", "notable_events": [], "data_quality_score": 26, "photos": [ { "url": "https://upload.wikimedia.org/wikipedia/commons/2/28/2-18th_Changi.jpg", "title": "2-18th Changi.jpg", "source": "commons", "attribution": "Photo by Not stated at source via Wikimedia Commons (Public domain)" }, { "url": "https://upload.wikimedia.org/wikipedia/commons/9/91/Allied_prisoners_of_war_after_the_liberation_of_Changi_Prison%2C_Singapore_-_c._1945_-_02_edited.jpg", "title": "Allied prisoners of war after the liberation of Changi Prison, Singapore -
