[2] Part of the national park was an original First Fleet grant and the park contains important historic and archaeological resources, including a homestead built in the 1820s, ruins of a stone windmill which is thought to be the oldest industrial building in Australia, convict-built dry stone walls, and a range of other features which reflect changes in the place since the early nineteenth century.

The national park also contains a number of Aboriginal sites which are of importance to our understanding of the Cattai area prior to European settlement.

[2][3] The Cattai Homestead, which was constructed around 1820, and its curtilage is listed by the National Trust and the Australian Heritage Commission.

The Hope Farm Mill on Hope Farm, which is also listed on the Register of the National Estate, was probably constructed around 1806 and is believed to be the oldest industrial site in Australia.
