[6] Castle Hill is situated in the traditional Wulgurukaba Aboriginal country.

The Aboriginal name Cudtheringa was recorded by Lieutenant George Poynter Heath, on advice from castaway James Morrill during a survey of Cleveland Bay in 1864.

[13] There is an obelisk at the top commemorating Robert Towns as the founder of Townsville.

As a result, the memorial stone from Robert Towns' grave was relocated to Castle Hill.
