Acorn Bank Watermill 2025
Cumbria
This small mine was worked for less than 10 years in the 1870s, until the miners broke into a cavity and the shaft was flooded. The pit that once housed a massive 30ft waterwheel, and the stone pillars that supported the wooden ‘launder’ or chute, which carried water to drive the wheel, are visible.

But unsuccessful mines are often the best preserved.
