Eylesbarrow mine was a
tin mine on
Dartmoor,
Devon, England that was active during the first half of the 19th century. In its early years it was one of the largest and most prosperous of the Dartmoor tin mines, along with
Whiteworks and the
Birch Tor and Vitifer mines. Its name has several variant spellings, such as Eylesburrow, Ailsborough, Ellisborough, Hillsborough etc. It was also known as Wheal Ruth for a short period around 1850. The extensive remains lie to the north of the
River Plym, less than north-east of
Drizzlecombe, on the southern shoulder of the hill called Eylesbarrow on top of which are two prominent
Bronze Age barrows.
