The suburb is one of the most historic sites in Australia's colonial history, being one of the five Macquarie towns officially proclaimed on 6 December 1810.[2] Governor Lachlan Macquarie recorded the following in his journal "the Township for the Evan or Nepean District I have named Castlereagh in honor (sic) of Lord Viscount Castlereagh",[2] Secretary of State for War and the Colonies 1805–1806. He, in turn, was named after Castlereagh in Northern Ireland. The official Government and General Order issued from Government House, Sydney was dated 15 December 1810.

The earliest known European development was the building of Hadley Park, between what is now Castlereagh Road and the Nepean River. Charles Hadley was given a grant in 1803, and his house, Hadley Park, was built c.1806. It still stands, largely intact. It has been said that it is difficult to overestimate the significance of this building. It was one of the earliest buildings in the colony and is "probably unique in its condition and setting". It is heritage-listed.[3]

Circa 1822, Nepean Park, also situated on Castlereagh Road, was built by convict labour for John Single. A notable two-storey farmhouse in the Georgian style, it was acquired by the Dixon family in 1934. It is heritage-listed at state and federal level.[4][5]

Castlereagh Post Office opened on 1 April 1857 and closed in 1967.[6]

After two hundred years, the rich river flats still provide for a thriving agricultural industry along the Nepean River. Many of Penrith district's pioneering families had originated from Castlereagh. The suburb's historical importance is reflected in its many surviving farmhouses, outbuildings, churches and cemeteries.
