Nantgarw
1910 - 1987

The two shafts at Nantgarw took five years to complete, the work taking place between 1910 and 1915. The depth of the shafts was 856 yards, which made them 2000 feet below sea levels. Shafts of such depths were unheard of at the time.

At the end of 1920's the colliery stood idle due to problems with geological conditions.

In 1947, at the time of Nationalisation, the colliery was reopened. A system known as "The Horizon Mining System" was employed in an effort to mine coal despite the geological problems.

Work ceased at Nantgarw and the colliery was closed 1987.
