Great Western Colliery

In Pontypridd, in the heart of the Welsh coalfield, is Hetty Shaft, one of the three mining seats that was founded by the Great Western Colliery Company.

Hetty's mine was first put into use in the mid-1870s. However, disaster struck on April 11, 1893 when a fire broke out 350 meters underground. The fire was able to spread rapidly due to the strong ventilation and the countless wooden supports. 63 miners were trapped like rats and did not survive the disaster. Their ages ranged from 14 to 61 years.


By 1923 the coal veins were exhausted, but Hetty remained as un upcast shaft for the group's other two mines, Ty Mawr and Lewis Merthyr. Coal mining was eventually stopped there in 1983.

The head frame and winding engine house are Grade I listed buildings, the fan house is grade II listed. Since the 2020s, volunteers have been working to, among other things, renovate the fan house and get the machines running again.
