The Darug people were the Aboriginal peoples to the area in 1788. The area was originally explored by British settlers in 1789 and the nearby eminence to the west of the Hawkesbury River was known by them as 'Richmond Hill'. The name was given by Governor Phillip, in honour of Charles Lennox, the third Duke of Richmond who was Master General of Ordnance in the Pitt administration. The local area was the third area to have European settlement in Australia after Sydney and Parramatta. The first 22 European settlers came to the area in 1794. They came to farm a total of in what is now Pitt Town Bottoms. They needed good farming land to help overcome the desperate need for food in the new colony. By 1799 this region was producing about half the grain produced in the colony. The Battle of Richmond Hill took place in May and June 1795 between the Darug people and the European settlers. It is perhaps the first time that the colonial authorities sent in the troopers and expressly stated their intent to 'destroy' the whole local Aboriginal population of an area. Around 1811 Macquarie established the five Macquarie Towns in the area: Windsor, Richmond, Castlereagh, Wilberforce and Pitt Town. One of the early settlers, James Blackman, built Bowman Cottage from brick nog, a common construction technique in the colony, using money borrowed from William Cox. The house was constructed between the years 1815 and 1818. James was unable to pay his debts and was forced to sell the property to George Bowman. The building was restored by the NSW Public Works Department and then became a Division of the Australian Foundation for the Disabled, providing employment for the disabled. During WWII the RAAF operated a top secret operations bunker from somewhere in Richmond. It was either half or completely underground. The location of this bunker is unknown but it has been reported that this bunker was identical to the Bankstown Bunker which is currently buried under a public park in Bankstown. It has also been reported that this bunker could still be intact. RAAF Base Richmond is a Royal Australian Air Force base at Richmond which was established in 1923. The air base is currently the home to the RAAF's transport squadrons. During the Vietnam War, logistic support and medical evacuations were supplied by the C-130 Hercules aircraft from RAAF Richmond.
