When Was Fort William Historical Park Created?

There is no "Fort William Historical Park." The correct site is Fort William Historical Site (formerly Old Fort William), located in Thunder Bay, Ontario, Canada. It is a reconstructed early 19th-century fur trade post of the North West Company. The site opened as a living history museum in 1973 after extensive archaeological research and reconstruction beginning in the 1970s. It operates seasonally (May–October) and is a National Historic Site of Canada.
