Castlebrook Memorial Park, a significant memorial site, was established in the 1960s, encompassing approximately 180 acres of land. As part of its development, a chapel and crematorium were commissioned in 1973, adding to the facilities and services provided by the park (Castlebrook Memorial Park). Notably, the site also features a monument that commemorates the historic Battle of Vinegar Hill, which took place in 1804. This monument stands as a tribute to the significant event and serves as a reminder of the historical significance associated with the area of Rouse Hill.
