Great Western Mine
Wales, United Kingdom
Great Western Colliery, which included the shaft known as the Hetty Pit, was a coal mine located at Hopkinstown, near Pontypridd, Glamorgan in South Wales. Operating from 1851 to 1983, the mine was the site of a major disaster in 1893 that killed 63 miners. The surviving structures, including the headframe and winding engine house, are now protected as a scheduled monument with several buildings holding listed building status.
