The Grenier mill was built in 1820 by François Grenier and classified as an historical monument in 1975. The excellent state of the original mechanism is one of the main points of interest. iPad terminals, archive photos and other interactive tools are at your disposal to learn more about the workings and history of windmills, particularly those in Repentigny. Free admission. Schedule: Wednesday to Sunday, from 1 PM to 5 PM, June 24 to the last weekend in August, as well as Labour Day, Les Journées de la culture and Thanksgiving weekends. Groups accepted upon reservation.
