The Third Class Precinct is positioned between the First Cemetery in the gully below and the Second Cemetery on the hill behind. In fact the Third Class Precinct was built in the late 1830s – then called the Healthy Ground – on the side of a hill facing west and overlooking Spring Cove. The west, which is where the sun sets, is associated with death in many cultures. Hence not only the quarantine cemeteries – and that includes the Third Cemetery on top of the same hill in what is now part of the North Head Sanctuary -, but the entire site of the Quarantine Station is appropriately positioned facing west given that it cannot escape the reality of the death in its historic role in isolating and curing life-threatening infectious diseases.
