was removed to prevent vandalism. The cap of the mill is a shallow dome which used to be covered with lead sheet, but also because of vandalism is now covered with aluminium. Between the cap and the top of the wall is a system of rollers running in a track plate allowing the cap to be rotated easily. There is a wind direction indicator on the roof which is continued into the interior, and a small repeat indicator at its lower end, so that the miller could set the mill without leaving his work. The lattice-type-sails are span counter clock-wise rotation (seen from outside the mill; most of all windmills worldwide rotate clockwise seen from inside the mill - from "under the wind") and with of canvas. The arched tower covers a very small diameter of and it has an "in cap" winding gear unusual for an English windmill, the cap being winded by a hand-operated winch having spur and worm gears. Restoration The mill has undergone three major reconstructions, one in 1776 when the mill shaft was modified, and the date carved in the tail of the shaft, and one in 1860 when the old curb and cap framing was altered. By 1910 it had ceased to function as a mill because the winding gear failed to operate, so that her last miller, William Haynes, was no longer able to turn the mill's cap round to make the sails face the wind. He abandoned the mill and moved to Harbury tower mill, one mile to the east. In the 1930s the mill was sometimes used for milling at 'prosperous' winds. Minor repairs to the sails and the wind vane took place. In the early 1950s one sail broke off and was restored years after. It was not until 1969 that a larger reconstruction of Chesterton Mill began again under the control of Warwickshire County Council, now responsible for its upkeep, and the reconstruction of the machinery. The windmill repairs were finished in 1971, and the mill reopened for a few days to the public each year in summertime (volunteers from nearby villages help run the open days and provide stewards for the event). In 2006 during an open day, one of the sails fell off the windmill injuring a visitor. Initially, following the incident, the area was roped off to prevent visitors approaching the windmill. The sails themselves were
