Ermatinger-Clergue National Historic Site

800 Bay St, Sault Ste. Marie, ON P6A 3G4, Canada
The Ermatinger-Clergue National Historic Site is one of the most important heritage attractions in Sault Ste. Marie, Ontario. This site includes two of the oldest stone buildings in the region, which tell the story of life during the early days of European settlement and the fur trade in Northern Ontario.
The Ermatinger Old Stone House, built in the early 1800s, belonged to Charles Oakes Ermatinger, a fur trader with the North West Company. It is considered one of the oldest surviving stone houses in Ontario west of Toronto. The house reflects the lifestyle of a wealthy fur trader and his family, offering visitors a chance to step back in time and see how people lived during that era.
Beside the Old Stone House is the Clergue Blockhouse. This log structure was originally built as part of the Hudson’s Bay Company’s facilities and was later used by Francis Hector Clergue, an American industrialist who played a key role in developing Sault Ste. Marie in the late 1800s and early 1900s.
Today, the Ermatinger-Clergue National Historic Site operates as a museum. Visitors can explore period rooms, historic exhibits, and seasonal programs that highlight the fur trade, early settlement, and the city’s industrial growth.
