The Elphin Windmill is the only fully restored windmill in the west of Ireland.
It is a round, three stage structure with a thatched revolving roof of organic rye. The sails are positioned into the wind by means of a pole attached to a cartwheel which revolves on a circular grooved track on the ground. The mill was originally used for grinding corn and other grains and now houses a visitor centre where the workings of the windmill are interpreted and demonstrated.
Also on site is an agricultural museum housing a threshing machine, a winnower and other machinery associated with the harvesting of grain.
