Universal Colliery

Universal Colliery was a coal mine located in Senghenydd in the Aber Valley, roughly four miles north-west of the town of Caerphilly. It was in the county borough of Caerphilly, traditionally in the county of Glamorgan, Wales.

Started in 1891, it became a ventilation facility for the Windsor Colliery in 1928 before complete closure in 1988.
