Old Changi Hospital in Singapore is one of Asia’s most notorious haunted sites. Built in the 1930s, it served as a military hospital before becoming a Japanese Kempeitai interrogation center during World War II — a period marked by torture, death, and disappearances.
After the war, it continued as a civilian hospital until its closure in 1997, leaving behind a decaying maze of empty wards, surgical rooms, and long, echoing corridors. Visitors and urban explorers report shadow figures, screams from the former operating theatre, and apparitions peering from shattered windows.
