Knowle Mill, better known today as Bembridge Windmill, is a preserved tower mill at Bembridge, Isle of Wight, England. Bembridge Mill was built c. 1700. It was painted by Turner in 1795. The mill was working by wind until 1913, having only been used for grinding animal feed after 1897. The mill was restored in 1935 & again in 1959, the latter restoration being funded by public subscription. In 1962 the mill was taken over by the National Trust.
