Castle Hill Mill Newent · Gloucestershire · England

Castle Hill Mill at Newent is a twentieth-century smock mill built for electrical generation. It differs from the older corn, drainage, and industrial windmills that make up much of the English windmill record because its documented purpose was to generate electricity. The mill is recorded at Castle Hill and is listed in specialist windmill gazetteers as a smock mill dating from the 1920s.

The structure is therefore part of the later history of wind power, using a traditional windmill form for a modern power-generating purpose. The site record does not present it as a former commercial corn mill, and its importance lies in the survival of a rare Gloucestershire smock mill associated with early twentieth-century private or local electrical generation. The mill remains part of the recorded windmill landscape around Newent and Castle Hill, preserving evidence for a non-agricultural use of wind power after the main period of wind-powered corn milling had largely passed.
