Warmley Mill Warmley · Gloucestershire · England

Warmley Mill is the windmill tower surviving within the former Warmley brassworks at Warmley. The industrial complex was founded by William Champion in 1743 and developed into one of the most important eighteenth-century brass and zinc works in the Bristol region. The surviving tower formed one of several sources of motive power used within the works, alongside water power, horse power, and later steam power.

The windmill tower is attached to the east side of the Dalton Young complex at Tower Lane. The scheduled monument description records it as a mid-eighteenth-century windmill tower, originally topped by a revolving cap and sails. Its exact working role is described cautiously: it may have assisted circulation of water, or it may simply have functioned as a corn mill. Other local industrial heritage material identifies it more directly as an industrial windmill used to drive machinery required for brass production, and by 1761 the Warmley works included a windmill for stamping ore.

The tower survived the decline and later fragmentation of the industrial site. The wider complex includes the former brassworks buildings, icehouse, clock warehouse, workers' housing, Warmley House, gardens, grottoes, and water-management features. The windmill tower now forms part of the Kingswood Heritage Museum setting, preserving a rare example of an eighteenth-century wind-powered industrial structure associated with non-corn-milling manufacture.
