Old Government House is Australia's oldest surviving public building. It was built by Governors John Hunter and Lachlan Macquarie between 1799 and 1815. Now managed by the National Trust (NSW), it has been restored and furnished to the Macquarie period (1810-1821). It boasts the nation's most important collection of early Australian furniture. Overlooking the Parramatta River, Old Government House sits on 260 acres of parkland. Ancient trees bear markings made by the traditional owners, the Burramatagal, and the site of the original 1788 Rose Hill settlement can still be seen. Other attractions include Governor Brisbane's bath house and observatory, the Government House Dairy and the Burramatagal Visitors Centre.
The National Trust of Australia (NSW) is an independent, non-government, community-based organisation. It was formed in 1945 to prevent the destruction of built and natural heritage. Today it is Australia's oldest and largest organisation for the protection of heritage.
