HISTORICAL NOTE: Medlyn Moor Mine was formerly an important stream ground which was developed underground from 1846 with the aid of a waterwheel that was used to sink a shaft 10 fathoms deep. 15 tons of tin were returned, but problems keeping the workings free of water resulted in the erection of a 30" steam engine in 1846 which continued in use until 1854 when the mine closed, but recommenced in 1873 when the existing engine house was built to accommodate a 40" engine. The mine finally closed in 1879. SW7066233555
