The Laxey Wheel (also known as Lady Isabella) is a large waterwheel built in the village of Laxey in the Isle of Man. Designed by Robert Casement, it has a 72-foot-6-inch (22.1 m) diameter, is 6 feet (1.83 m) wide and revolves at approximately three revolutions per minute.
It was built in 1854 to pump water from the mineshafts and named "Lady Isabella" after the wife of Lieutenant Governor Charles Hope who was the island's governor at that time. The Laxey Wheel is the largest working waterwheel in the world. The wheel was used to pump water from the Glen Mooar part of the ‘Great Laxey Mines’ industrial complex.
