The Royal Victoria Hospital, or Netley Hospital was a large military hospital in Netley, near Southampton, Hampshire, England. Construction started in 1856 at the suggestion of Queen Victoria but its design caused some controversy, chiefly from Florence Nightingale. Often visited by Queen Victoria, the hospital was extensively used during the First World War. It became the 28th US General Hospital from 1944 to 1945 during the Invasion of Europe. The main building - the world's longest building when it was completed - was entirely demolished in 1966, except for the chapel and former YMCA building which still survive. The extensive outbuildings, which once occupied a vast acreage of land to the rear of the main building, finally succumbed in 1978. The site of the hospital can be seen and explored in Royal Victoria Country Park.
