The Pointe-Claire Windmill (French: Moulin à vent de Pointe-Claire) is a windmill in Pointe-Claire, Quebec, Canada. It is the oldest windmill on the island of Montreal and one of 18 remaining windmills in Quebec.Like most mills in New France it was built to a French design, a cylindrical stone tower with a movable roof which could be turned by a tail pole to face the sails to the wind. The mill had two doors, to provide an exit regardless of which ways the sails faced.
