In 1828, the Governor of New South Wales Sir Ralph Darling subdivided the area, then known as Woolloomooloo Hill, into large allotments which he granted seventeen estates to favoured subordinates and leading businessmen. They built a series of grandiose mansions with sprawling gardens of up to ten acres (4 ha). The remnants of these gardens helped give the area its leafy character, and many of the mansions are commemorated through street names such as Roslyn, Orwell and Kellett. Most of the grand estates were ultimately subdivided with all but a handful of the great houses demolished. One of the surviving homes, located nearby in the suburb of Elizabeth Bay, is Elizabeth Bay House, a quintessential example of Australian colonial architecture. Others, now used for other purposes, include Tusculum in Manning Street and Rockwall. A prominent past resident of this era was David Scott Mitchell.
