The remains of the old Wheal Betsy mine lie alongside the Okehampton to Tavistock road. An early mine, probably originating from about 1740 although it could have been earlier, it produced principally lead and silver rather than tin. In the early days the ore would have been smelted on site using peat charcoal. It closed in the late 1700's but was re-opened in 1806 and was then worked by water power The engine house was built in 1868 and the mine remained in operation until 1877 using steam power. The chimney leans at a precarious angle when viewed from the east although it looks normal from the west; this has given it its nickname "The Leaning Tower of Dartmoor". In 1967 the ruined engine house and stack were acquired and made safe by the National Trust as a memorial to the mining industry of Dartmoor.
