Pinchbeck West Mill Pinchbeck · Lincolnshire · England

West Mill was built in 1812 beside the River Glen at Pinchbeck West. It is also recorded under the alternative names Glenside Mill and Speed's Mill. The mill was a wind-powered tower corn mill and stood with a bakehouse close to Small Drove Lane, serving the local grain-milling economy of the south Lincolnshire fenland.

The mill worked by wind until 1931. Twentieth-century photographs record the standing tower in the period after wind working, and the windshaft was recorded on the ground in later mill-photography collections. Milling did not end immediately with the loss of wind power: Glenside Mill continued to use modern milling machinery until the 1970s. By the late twentieth century the tower had survived as a distinctive preserved structure, with a noted lean and later replica cap. Together with Northgate Mill, it represents one of the surviving windmill structures in Pinchbeck.
