Old Changi Hospital, Changi, Singapore
In 1942 this hospital and barracks was captured by Japanese soldiers and converted into a prison for British soldiers and their allies. There, the Japanese soldiers brutally tortured their prisoners, resulting in a lot of death. Today the building is no longer used, but visitors claim to hear screams and moans throughout the building and there have even been reports of the ghost of a young boy who stares into space, inflicting sadness on all who see him.
