By 1811 Governor Lachlan Macquarie established the five "Macquarie Towns" in the area. They are Windsor, Richmond, Castlereagh, Wilberforce and Pitt Town. Many of the early 19th century buildings still survive today. Ebenezer has the oldest surviving church and school building in Australia. Windsor District Council was formed in 1843 and disbanded in 1846. In 1871 the Borough Council of Windsor was founded and the Richmond Borough Council followed in 1872. The two councils amalgamated in 1949 to become the Municipality of Windsor. Colo Shire Council was established in 1906 and joined Windsor Municipal Council from 1 January 1981 to become Hawkesbury Shire Council. On 1 July 1989, Hawkesbury became a City.
