A member of 'Kernow Matters To Us' (KMTU) lost two ancestors in the Levant disaster. Their wives were evicted within a couple of weeks being unable to pay the Bolitho Bank of Cornwall the rent for their cottages and ended up in the Penzance Union Workhouse.
Here's the background to that fateful day:
The cliffs of St Just provide a dramatic backdrop the for the scene of one of Cornwall's worst mining disasters in recorded history.
Perched on the edge of the cliffs remain several buildings which offer insight into the work of the men and women who risked their lives at Levant Mine; commonly known as 'Queen of Cornwall's submarine mines'.
Hidden beneath the sea is a labyrinth of tunnels which stretch a mile out, once used to extract tin and copper from the earth.
The mine was operational between 1820 and 1930 and produced 130,000 tonnes of copper, 24,000 tonnes of tin and around 4,000 tonnes of arsenic. The earliest records of copper being mined at the site date back to 1670. It was a lucrative business, with some £2.25 million returned.
