the mariner and trader, William Douglas Campbell, by Governor Macquarie in 1815. The homestead built in stages between 1817 and 1827, associated structures, gardens, landscape features, and remnant grazing paddocks have historical, social, aesthetic and technical significance at the State level. Harrington Park demonstrates the layout of a gentleman's estate with views and vistas afforded to and from the homestead over the landscape and important access routes. The remnant cultural landscape has many features of individual significance such as the original cottage, early homestead, garden, entry drive from the old Cowpastures Road (Camden Valley Way), the 1957 garden studio and the remaining estate area. Historically the quintessential landscape character – based on the traditional juxtaposition of homestead area, with its dominant garden, and cleared pastureland beyond – represented one of the best examples of this intentional contrast as well as the siting of a homestead group on a landform summit in the Cumberland Plain / Camden area. The place currently retains some key historical visual relationships – vistas to Orielton, Studley Park, the spire of St. John's Church, Camden and the Razorback Range. Its historical relationship to other nearby early grants (Orielton & Oran Park) and its place in the development of the local area can still be appreciated. The place currently retains its historical local prominence and serves as an important local landmark. The property has strong associations with members of the ruling class in early NSW and the familial dynasties of the Campbells (1810s – 1850s); the Rudds-Brittens (1870s – 1920s) and the Fairfax publishing family 1940s – 2005). The place has considerable capacity to demonstrate its development from the early 1810s to the present. It is of considerable scientific interest on account of its archaeological research potential. Harrington Park was listed on the New South Wales State Heritage Register on 22 December 2006 having satisfied the following criteria. The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales. Harrington Park estate is of State significance as the main part of a grant to William Douglas Campbell by Governor Macquarie in 1815. This land encompasses the house that Campbell built in stages from 1817 to 1827. The property was part of a landscape dotted with similar gentlemen's properties established on generous grants from colonial governors and lieutenant governors. However, the house is one of the earliest in the vicinity
