 In its time the wheel has been used for various purposes, including pumping water to the Groudle Hotel (designed by Hugh Ballie-Scott) and providing power for the fairy lights that ran through the glen from the entrance to Lhen Coan, terminus of the Groudle Glen Railway.Latterly its function has become entirely aesthetic.The wheel house was rebuilt in 1954 when the glen was enjoying something of a renaissance as a tourist attraction, and rumours abounded at this time that the wheel house was haunted.
