Governor Macquarie chose the National Trust Centre as a military hospital in the 1800's. Now it houses tea rooms, a National Trust Shop, and the S.H. Ervin Gallery. The gallery concentrates on Australian art and architecture from a historical perspective, with works from 19th and 20th century Australian artists. Exhibitions are changed regularly and are always of a high standard. Some of the artists that the S.E. Ervin Gallery have housed include Lloyd Rees, Sidney Nolan and Russell Drysdale.
