There are parts of the Coal Mines Historic Site that are no longer accessible.
And perhaps none is more intriguing than the Main Shaft.
Originally around 92 metres deep, the shaft constantly flooded. Pumps had to operate continuously to remove water, initially powered by groups of men and later by a steam engine.
Convicts were lowered into the mine using a windlass. One man sat across a short iron bar holding the chain, while another sat opposite him, across his knees.
Then they were lowered into the darkness.

Standing beside the remains of the Main Shaft today, knowing what once happened beneath your feet gives this landscape an entirely different meaning.
