Keston Windmill

Keston Windmill was built in 1716. William Ashby, the Westerham millwright fitted new sails and repaired the breast of the mill in December 1836. The mill was working by wind until either 1878 or 1900. The mill was built to grind corn into flour. The mill is privately owned and preserved with its machinery intact, but not in working order. It is not generally open to the public.

Keston Mill has a three-storey body on a single-storey roundhouse. The roundhouse enclosed the trestle and the date 1716 is carved on the main post. It had four double Patent sails carried on a cast-iron windshaft. The mill is winded by a tailpole. The wooden brake wheel drives a cast-iron wallower, which drives a cast-iron great spur wheel with wooden cogs. This drives two pairs of underdrift millstones in the breast of the mill. The mill also has a flour dresser (bolter).
