Sir John Johnson Manor House

Along the Raisin River lies one of the oldest homes in Ontario. This Georgian-style house was built for Sir John Johnson (a soldier, Loyalist and public servant) between 1784-92. This site was chosen because it is a natural location for water-powered mills. The house is now a National Historic Site, dedicated to preserving local history through archives and tours.
