Windmill Tower
William Champion used any source of motive power he could lay his hands on one of these was windpower. There remains as part of the museum building, William's Windmill tower. This is a rare surviving industrial windmill. It was never used to grind corn but to grid the ores from which cooper and zinc were acquired. The tower is complete but the floors which were in situ until the early twentieth century are now gone, as are the cap and sails. Never the less vistors are impressed with the sheer size of the remaining structure with its metre thick walls. The tower has recently been restored and should stand for another 100 years or more without much attention.
