also associated with the Prince Henry site. Historical archaeological evidence, including sandstone drains and road alignments, of the former Working Patients Dormitories, also continues to exist to the south of the Prince Henry site. Modifications and dates The Prince Henry site, Little Bay has undergone numerous and continual modification and change since its inception. Four key phases of development reflect the site's transition from the Coast Hospital, built for the isolation and treatment of infectious diseases, to the Prince Henry Hospital, which later became a major general and teaching hospital. Establishment and Early Consolidation of the Coast Hospital, 1881-1914 This phase represents the first use of the site in 1881, for temporary accommodation as a response to an outbreak of smallpox. One hundred and seventy-five hectares of land at Little Bay were reserved for quarantine purposes, ultimately leading to the establishment of an isolation hospital and sanatorium. The layout and design of the Coast Hospital reflected hospital design practices of the time including separate locations for infectious patients and the sanatorium. Apart from archaeological evidence of the Coast Hospital and the Male Lazaret, only a small number of features survive from this period, including the Dam, the former Coast Hospital Steam Laundry, Pine Cottage, Pine Avenue (historic road alignment, sandstone kerbing, retaining wall and pine trees), the Artisans' Cottages and buildings from the Infectious Diseases Division (Ward 16, the Kitchen and Boiler House) which have been incorporated into the Institute of Tropical Medicine. A number of other historic road alignments remain including, the loop roads to the Infectious Diseases Division and Nurses (14) Quarters (Sewing Cottage) and to the Matron Dickson Nurses Home and the Bush Wards, the road associated with the Artisans' Cottages, the Coast Hospital Road and the Cemetery Road as does the Second (North) Cemetery. Expansion of the Coast Hospital, 1915-34 This phase represents a period of growth that began after the then Board of Health unveiled plans for considerable expansion of the Coast Hospital, which was to include the construction of up to 20 new wards, each of which would contain 50 beds. This area was to be known as the "Flowers Hospital". Although only six of the wards were completed, due to a change of government in 1917, they contributed to the hospital becoming the largest in New South Wales by 1929.
