On the 14th of October 1913 and explosion occurred at the Universal Colliery in Senghenydd near Caerphilly in South Wales. 440 men and boys lost their lives that day in what was to become the UK's greatest mining disaster.
Two names on these tiles that surround the memorial bear the same name, Charles Baker of 18 Alexandra Terrace, Senghenydd. A father and son. It was not unusual for children of 14 to be taken underground by their fathers to work as 'collier's boys'. Brothers also suffered the same fate.
There are also plaques remembering those disasters where more than five perished. It includes the 144 that died at the Aberfan Disaster in 1966.
