The Mill on the Fleet was built in 1788 as a cotton spinning mill and restored as a visitor centre by Dumfries and Galloway Council in the 1980’s. The water wheel on the gable end was used to drive the machinery to spin the cotton. The separate longer wheel was connected to machinery in another mill building, now ruined, but both mill wheels have now been reconnected to the original water supply and it is hoped that their motion will be harnessed for practical use in the future. As well as the wheels, the mill has displays of the Fleet Valley, a welcoming café, a shop and special exhibitions.
