'Windmill (disused).'{1} 'Glenmill.'{2} Glenside Mill is dated 'RT1812' and was built using the principal gearing from an old marsh mill in Bourne Fen. It was raised by another storey at some stage and worked by wind until 1931. The last pair of sails were damaged by a gale and were removed in 1932-3. It was dismantled c.1945, continuing to work using modern milling machinery driven by engine. It remained in use until the late 1970s. There were four spring sails mounted on stocks in a poll end, which drove two pairs of stones. The tower has developed a serious lean over the years and one side is now almost vertical. {3}{4}
