Fort William Historical Park (formerly known as Old Fort William) is a Canadian historical site located in Thunder Bay, Ontario, that contains a reconstruction of the Fort William fur trade post as it existed in 1816. It officially opened on July 3, 1973.
The site is located on the banks of the Kaministiquia River at Point de Meuron. This point is a few kilometres upstream from the original fort's site, Fort Kaministiquia, which has been built over as part of the city of Thunder Bay. Point de Meuron has separate historical significance, as it was the location of an Hudson's Bay Company post of the same name. (Wikipedia)
Named in 1807 after NWC chief superintendent William MCGILLIVRAY, Fort William occupied a pivotal place in the company's vast trading network. ... This occupation, combined with major financial difficulties, led to the NWC merger with the HUDSON'S BAY CO in 1821.
