Administrative/Biographical history: Oakeley Slate Quarries Co. Ltd was created in 1883 as an amalgamation of the Upper (Hollands) and Middle quarries (Gloddfa Ganol), Blaenau Ffestiniog, Merionethshire. Later, Cwm Orthin and Nyth y Gigfran quarries made the Oakeley Quarries the third largest in the industry, employing around 1700 men. Oakeley had about 30 workers' cottages on-site, and a hospital. The quarry used the London and North Western Railway, loading at Pant yr Arfon. By 1937, due to the decline in the slate industry, the quarries only had 765 workers. Oakeley closed in 1970, but later reopened as the Gloddfa Ganol Quarry, with a visitors' centre, and the Oakeley Quarry.
