Great Western Mine

The mine, originally called, "Gyfeillon Pit", was begun by John Calvert, an engineer from Yorkshire, in August 1851.

On Tuesday 11 April 1893 a fire in the colliery led to the deaths of 63 men and boys.

[2] The Inspector of Mines list for 1896 recorded a total of 475 men working at the Great Western No.

[3] In 1928 the colliery came under the ownership of the Powell Dyffryn Coal Company and remained so until the mines were nationalised in 1947.

[9][10] It was originally intended to incorporate the site into the Rhondda Heritage Park, but its future is now unclear.

The Hetty winding house and engine are now being renovated by volunteers under supervision of Mr Brian Davies of the Pontypridd Museum.
