Overview: Situated on the eastern coast of the Isle of Man, the village of Laxey is known today as a tourist destination, but as archaeologist Ben Robinson finds out, it wasn’t the beaches and the mountains that attracted Victorian tourists, but an engineering marvel - the biggest waterwheel in the world. Ben meets local resident Matthew Boyd who is repairing and restoring the 22-metre-wide great wheel and finds out how it transformed this small mining community to one of the most successful in the British Isles. He meets mining historian Peter Geddes who takes Ben deep underground to experience first-hand some of the conditions the miners faced.
