Martintown Grist Mill Doors Open Stormont, Dundas and Glengarry

Martintown Grist Mill

This mill along the banks of the Raisin River is a rare surviving example of a mid-19th century gristmill. It is also noteworthy for its early turbine-style technology that used horizontal waterwheels powered by a water course running through the building. The mill has a local history museum and hosts a farmers’ market and local artist exhibit in the summer.
