Bute Colliery, Treherbert, 1851

Sunk by W.S. Clarke at Cwmsaebren on the 16th of October 1851 for the Marquis of Bute. This was one of the two collieries which pioneered the first attempts to work the famous Rhondda "Steam" coal seams. Notice the early "timber" headgear.

The Upper four feet was reach at a depth of 125 yards. A second shaft was sunk between 1853 and 1855 to serve as an upcast. This was the first steam coal colliery in the Rhondda and on the 21st of December 1855 from this colliery the first consignment of Rhondda steam coal was sent to Cardiff docks.

From the Inspector of Mines list 1896, work was suspended at this colliery and there were only seven men employed.
Later it became part of the Ocean & United National Collieries Ltd.

It closed in 1926
