Further Information

Completed in 1857, the mill, owned by the ‘Bangor and Portmadoc Slate and Slab Company’, was built to process slate slabs from the unsuccessful and short-lived Gorseddau Quarry nearby. It was powered by an 8 m diameter waterwheel and was served by two tramways: one bringing slate from the quarry, the other taking the finished product to the port at Porthmadog. The company went out of business in 1871.

  2. This is quite intriguing, a piece of industrial dereliction that has been preserved in a derelict state. It’s something you see with castles, but not with industrial buildings.

  4. A fantastic place to look round. Maybe could do with a couple of information boards for the younger generation to get An idea of all the hard work that would have been done.
    My only concern is the amount of Japanese not weed on the river that runs through the site
