Alexandra Hospital (AH) is a hospital located in Queenstown, Singapore that provides acute and community care under the National University Health System. The hospital's colonial-style buildings were constructed in the late 1930s on 110,000 square metres (1,200,000 sq ft) of land. Under British rule, it was known as the British Military Hospital and was the site of a massacre in February 1942 by the Japanese as they took over Singapore in World War II. After the liberation of Singapore, the hospital was returned to its British administration, before being handed over to the Singapore government on 11 September 1971. Since then, it has gone through four changes of administration, most recently on 1 June 2018, to a team of long-term stewards under the National University Health System.
