Ferndale Colliery
Ferndale, United Kingdom
Ferndale Colliery was a major coal mining complex comprising nine interconnected coal mines that operated in the Rhondda Valley, South Wales, from 1857 to 1959. Established by coal owner David Davis, it became one of the most significant steam coal producers in the South Wales coalfield. The colliery was notable for two major explosions in 1867 and 1869 that killed 231 miners, and for containing the deepest pit in the Rhondda Valley at 606 yards. After nationalisation in 1947, the complex gradually closed due to economic pressures, with the final closure in 1959 ending over a century of coal extraction.
