This view from the quarry incline is looking down on Porth y Nant and the bay in 1930s. Hundreds of tons of granite were quarried in the valley on a daily basis and ships regularly moored up alongside one of three jetties in the bay below to be loaded with the setts and crushed stone. The bay had no shelter from the westerly winds and vessels were occasionally wrecked during storms. There was no road access to the valley and goods mostly came in and out by sea.
At their peak the three quarries employed around 110 men. Labourers, trammers and brakemen brought the granite down to the crushing mill and docks.
