Gladesville Mental Hospital
Sitting on the appropriately named Bedlam Point, Sydney’s first ever psychiatric hospital opened its doors in 1838, and racked up ghost story after ghost story until it eventually closed in 1997. The facility was unkindly known as the Tarban Creek Lunatic Asylum when it began doling out its infamous brand of sadistic mistreatment – the hospital, today abandoned and caked in a thick layer of graffiti, even contains a mass grave of more than 1,000 anonymous corpses who died there.
