The clue is in the title, yes they made bricks here and they would have been shipped out by sea from the quay here. Across the water and into the strait itself slate would have been the main outgoing cargo and I had made it my intention to search out the quay serving the Penrhyn quarries and I make a rather exciting discovery. There is a cycle track from the quay following the old mineral railway through Bethesda and on to Ogwen lake. I also think I shall bite the bullet and buy that bike I have had my eye on for a few months.
