Government House was constructed between 1837and 1845. It is the most sophisticated example of a Gothic Revival building in New South Wales. The ground floor State Rooms include the dining room, drawing room and ballroom. These contain an outstanding collection of 19th and 20th century furnishings and decoration that reflect changing styles and the differing tastes of the Governors and their wives. The first floor includes State Apartments that were used by the Governor, visiting members of the Royal Family and other Heads of State.
