Fort Nisqually was an important fur trading and farming post of the Hudson's Bay Company in the Puget Sound area, part of the Hudson's Bay Company's Columbia Department. It was located in what is now DuPont, Washington. Today it is a living history museum located in Tacoma, Washington, USA, within the boundaries of Point Defiance Park. The Fort Nisqually Granary, moved along with the Factor's House from the original site of the second fort to this park, is a U.S. National Historic Landmark. Built in 1843, the granary is the oldest building in Washington state and one of the only surviving examples of a Hudson's Bay Company "post-and-plank" structure. The Factor's House and the granary are the only surviving Hudson's Bay Company buildings in the United States. Foundation The Hudson's Bay Company expanded to the west coast by forming the Columbia District to oversee its operations in what was known by American interests as the Oregon Country. Forts would be built in the District at central fur gathering locations, accessible to a large number of tribes. In 1824, Fort Vancouver was built a few miles from the Columbia River to the south, and Fort Langley was built in 1827 on the Fraser River to the north. The Cowlitz Portage, an overland and shortcut route, was soon created, and thus a vital link between the two forts was established. After the attack and murder of Alexander McKenzie and four men in his party on this route (in revenge for which the HBC leveled an unrelated S'Klallam village, killing twenty-seven people ), it was determined a fort located at a halfway point was needed for safety and security reasons. The new midway location was at Nisqually, chosen for its excellent ship anchorage, its convenience for overland travel, the friendliness of local tribes and its prairies for grazing animals and growing crops. Located near the mouth of Sequalitchew Creek on the plains north of the Nisqually River Delta, in the present town of DuPont, Washington, Nisqually House was built in April 1832. It was a 15 by 20 feet warehouse. The staff was only three men with a few supplies left behind to manage it. It was notably the first European trading post on the Puget Sound. Operations One year later, in May 1833, Chief Trader Archibald McDonald returned with William Fraser Tolmie and seven men to begin the construction of a permanent
