Adventist Health Castle, originally known as Castle Memorial Hospital, opened on January 16, 1963, with 72 beds and 14 bassinets. The establishment of the hospital was the result of a community-driven effort that began in 1953 to bring healthcare services to the Windward side of O'ahu, which at the time only had part-time ambulance service.
