Braich Goch slate quarry, Corris, 1975 showing the slate tips in the background where work commenced on the 4th of July 1975 to level the tips in a £ million slate tip land reclamation scheme, which will take two years to complete. The site was landscaped, obliterating the workings, the mill and buildings. The main road now runs over the site of the mills and the Corris Craft centre and King Arthur's Labyrinth now sits above the former waste tip and mill. My dad, Ken Rowlands remembers being told when he was a boy that the large electrical switchboards on the Titanic were made of welsh slate from Braich Goch slate quarry. Slate was known to be a very good electrical insulator. A local author and friend, the late Sara Eade researched and wrote a very good book about the Corris slate quarries, including Braich Goch. It's called " Within These Hills", a study of Corris Uchaf.
