Other than the spectacular setting of its surviving engines houses on a precipitous cliff-side overlooking the east shore of Mount’s Bay, Wheal Trewavas was never a major Cornish mine. It opened during the 1820s and closed in 1847 - made reasonable profits for a while, and then losses leading to closure.
As a reasonably priced history of a typical mine this is excellent and I would recommend it to anyone interested in learning how Cornish mining operated and was financed. If you think ‘Poldark’ (the books or the TV series) exaggerate, then read this!
