The tower mill originated in written history in the late 13th century in western Europe; the earliest record of its existence is from 1295, from Stephen de Pencastor of Dover, but the earliest illustrations date from 1390. Other early examples come from Yorkshire and Buckinghamshire. Other sources pin its earliest inception back in 1180 in the form of an illustration on a Norman deed, showing this new western-style windmill. The Netherlands has six mills recorded before the year 1407. One of the earliest tower mills in Britain was Chesterton Mill, Warwickshire, which has a hollowed conical base with arches. The large part of its development continued through the Late Middle Ages, towards the end of the 15th century tower mills began appearing across Europe in greater numbers.
