Building housing the New South Wales Legislative Assembly and Legislative Council, built as the northern wing of Sydney Hospital, and much added to over nearly 200 years.
Although built as part of Sydney hospital, the northern wing that became Parliament House was never used only for medical purposes, being put to work as a temporary court and judges' chambers. From 1829 it was used for Executive Council meetings, and with responsible government, the building needed extensions. Many additions followed, with a major modern building added to the back of the building in the 1970s.
