At eight minutes past two in the morning a huge explosion ripped through one of the sections of the Gresford coal mine near Wrexham. In one of Britain’s worst coal mining disasters, 266 men were killed. only eleven bodies were ever recovered from the mine (eight miners and three of the attempted rescuers). The damaged sections of the mine were sealed with most of the bodies inside.
The rest of the mine was re-opened in 1936 and operated until 1973. The old winding wheel was preserved as a memorial after the pit closed.
