One of the most striking location for a tin mine in Cornwall, equal to the Crowns Engine Houses at Botallack. The Towanroath pumping engine house lies on the North Cornwall coast just west of St. Agnes. It was constructed in 1872 and is a Grade II listed building in the stewardship of the National Trust. It pumped water from the 600 feet deep Towanroath Shaft of the Wheal Coates Copper and Tin Mine.
