[1] Following the discovery of the area, the colonial gentry soon regarded it as rich, fertile and suitable land for livestock grazing and pastoral pursuits.

The low rambling hills and wide expanses of grass flats were devoid of difficult vegetation and reminded the colonists of the familiar landscape of an English gentleman's park.

[1] In 1815, Governor Macquarie granted an 809-hectare (2,000-acre) parcel of land to Captain William Douglas Campbell, a member of the British merchant navy, who named the estate Harrington Park.

A wealthy grazier and one of the largest landowners in the Campbelltown district, Moore lived at Oran Park with his wife Anne and large family (of some 12 or so children) until the construction of the nearby Badgally house was complete.

When the family moved in 1882, Moore leased the imposing two-storey Oran Park house (with wrap-around verandahs, rear basement, octagonal tower and established gardens) to Thomas Cadell who operated the property as a dairy farm.

[1] After Robbins death in 1945, Oran Park was sold to Daniel James Cleary (who established the Oran Park Raceway, west of the property), sold again to Sydney merchants Arthur Raymond Booth and Robert Leslie Booth later in 1946 and then again to Camden farmer John Thomas Vivian Frost in 1947.

[1] After another failed development attempt and a succession of different owners, Oran Park was purchased in 1969 by the Honourable Lionel John Charles Seymour Dawson-Damer.

Currently owned by Hixon Pty Ltd (as of August 2013), Oran Park is the subject of the Catherine Fields (Part) Precinct land release area.

Its siting in the landscape makes Oran Park house a visually dominant structure and affords it views from and towards the surrounding historic estates.

The older driveway runs on a diagonal from south-east to north-west, from close to the corner of the former Cow Pasture Road (now Camden Valley Way) to the homestead.

This was lined in the 1920s with inter-planted avenue of South African yellowwood / outeniqua (Afrocarpus falcatus) and native Port Jackson cypress pine (Callitris rhomboidea).

Originally constructed in the Victorian Italianate style, the house underwent significant modifications in the Inter-War period and now has a Georgian Revival appearance.

[1] Oran Park is of state heritage significance for its association with a number of prominent people, including: William Douglas Campbell (recipient of original grant and owner of Harrington Park, 1815–27), Edward Lomas Moore (wealthy grazier and large landholder in Campbelltown district, 1871–82) and the Honourable John Dawson-Damer (engineer and motor racing enthusiast, 1969-2002).

Oran Park is of state heritage significance for its association with a number of prominent people, including members of the colonial ruling class of NSW in the 19th century.

[1] The Oran Park property was originally part of a 2000-acre land grant, awarded by Governor Lachlan Macquarie to William Douglas Campbell in 1815.

The establishment of Oran Park house on a prominent hilltop location in a rural setting reflects the landscape design principles that were practised in England in the early 19th century.

The siting of the house in the landscape, reminiscent of the summit model, provided its residents with sweeping views of the countryside and vistas to and from Oran Park to neighbouring colonial estates in the Cowpastures district.

[1] However, Oran Park is widely recognised as an early cultural landscape and has some social significance for the greater Camden district (once the Cowpastures).

Established in the 1830s, Oran Park is a remnant country estate that reflects the landscape design principles that were practised in England at the time.

[1] The siting of an imposing mansion-style house on a dominant natural hilltop or ridgeline was a British design type used throughout the Cowpastures district during the early to mid-19th century.
