The Hills District Historical Society was formed in July, 1967. Its first President was Councillor Fred Caterson and its first Secretary was Bob Martin. These two early pioneers of the Society had discussed the need for a local historical society and were the ones who launched the new Society. They were concerned about the loss of historic buildings and the need to preserve the built and written heritage of the local area.
In 1974, a Museum was established in the basement of the former RSL Club/Castle Hill Community Centre. (opposite Castle Towers Shopping Centre) The Museum remained there for around 30 years. When the Community Centre was demolished, the Museum was closed until a new location and facilities could be found.
The new Museum opened its doors to the public in March, 2007 at its present site, The Powerhouse Discovery Centre, Castle Hill.
After many long months of negotiation with Council, the Society celebrated the opening of their new permanent home in November 2010 at Building 10, The William Thompson Masonic School, Balcombe Heights Estate, Baulkham Hills.
The Museum houses a wonderful collection of artefacts displayed thematically, that tell the story of what early life was like for people living in the Hills District. The Museum’s resources include and extensive photographic collection, library books and facilities for research. A comprehensive collection of files on a range of topics covers people, places and events that are historically important to the Shire.
