Botallack

Botallack is just north of Cape Cornwall.

Yes, the abandoned buildings at Botallack were used for the Poldark family mines of Wheal Leisure. In real life it’s called Wheal Owles and Wheal Crowns.

Botallack is a submarine mine with tunnels extending under the sea in places for half a mile. Over its recorded lifetime the mine produced around 14,500 tonnes of tin, 20,000 tonnes of copper and 1,500 tonnes of arsenic. An estimated 1.5 million tonnes of waste would have been dug up with the minerals. It is unclear how far back mining activity goes in this location. Early records date from the 1500s. Some archaeological evidence points to mining here in the Roman era or even as far back as the Bronze Age.
