Watson's Mill

Built in 1860 along the shores of the Rideau River, Watson’s Mill remains active as a water-powered flour mill. Nearby Dickinson House, built in 1867, displays the heritage home of the past mill owners. Dickinson Square is the only industrial heritage site in Ottawa. The site comes to life through tours by costumed interpreters and milling demonstrations.
