Water mill; Watermill
A place where the passage of water onto paddles - falling or being pushed vertically or horizontally - turns, through mechanisms, millstones to grind a material down. Such materials might be crops, for animal or human consumption, chemicals or stone, (such as flint), which require reduction in size or the removal of un-necessary parts. (See also threshing barn). Gathering ponds, millraces, dams and sluices are all parts of a watermill complex. The earliest watermills in the region are connected with the Romans on Hadrian's Wall - there were mills at Cawfields and Chesters, (both Northumberland).
