In the 1850s quarrying seems to have been at full swing in both Abereiddi and Porthgain with a new quarry opened up near the harbour, again on the same lines as at Abereiddi where the slate had to be lifted out of an ever deepening pit and, as that quarry was on the higher ground it then had to be lowered down to the workshops at the harbour level. This was very costly as eight tons of slate had to be quarried in order to produce one ton of slabs or slates. On top of that the seven tons of waste had to be transported to the cliff edge for tipping into the sea.
This is one of the old quarries, but this one was for granite.
