Maud Foster Windmill is a seven-storey, five sailed Tower mill located in Boston, Lincolnshire. She is one of the largest operating windmills in England being 80 feet (24.38 m) tall to the cap ball.

In 1987 the mill was bought by James Waterfield and his family who restored her in 1988 to fully working order and is probably one of the most productive windmill in all England.  The mill is open to visitors who may climb all seven floors and see the milling process in action and enjoy views of the town from the balcony. 

All of the products they produce are available in the mill shop
