Aboriginal people from the Cabrogal tribe, a sub-group of the Gandangara tribe, have lived in the Fairfield area. European settlement began in Fairfield in the early 19th century. Horsley Park was originally part of Colonel George Johnston's property "Kings Gift", which was given to him by
Governor King for his part in putting down the
Irish Rebellion at
Vinegar Hill in 1804. After his death it passed to his daughter Blanche who in 1829 married Major George Nicholas Weston. He built an
Indian colonial style homestead on the property and named it "Horsley" after his birthplace in
Surrey,
England. Horsley Homestead is one of the few remaining early colonial buildings in the Fairfield district today protected by The Australian Heritage National Trust. In 1959, the Horsley Drive (so named because it leads to Horsley Park) opened up as a continuous route from
Lansvale. Horsley Park Public School was opened in 1931. During the
Sydney 2000 Olympics, Horsley Park became the venue for events of
equestrian. Today, Horsley Park is known to have a rich Italian and Maltese heritage residing. It is also known for being the original location for the formation of Club Marconi. == Heritage listings ==
