The chief Hudson's Bay Co. fort at Winnipeg. Was built on site of N. W. C. Fort Gibraltar in 1822 after the union of both companies in 1821. It was a rough affair with wooden palisades, known at first as The Company's Fort, or Fort Gibraltar (so called because it was built on site of N.W. Co. Fort Gibraltar.) It was named fort Garry by Governor Simpson in 1823 after a Hudson's Bay Co. councillor. The fort consisted of the buildings erected by the North West Co. after the destruction of Fort Gibraltar and some additions and palisade. This fort was known as the first fort Garry. Was situated near the banks of the Assiniboine and Red rivers. Much of the land was washed into the Assiniboine river, especially by the flood of 1826, and in 1852 what was left of the fort was pulled down.

The second Fort Garry was begun in 1835, a little removed from the site of the first fort Garry. It was known as Upper Fort Garry. Built by Governor Alexander Christie. It was substantially built, covered a space 240 x 280 feet enclosed by a solid stone wall and four large round bastions of solid masonry at the corners. It was sold to the city of Winnipeg in 1882. Only the north gate now remains as an historical site. A picture of the second fort Garry is given in Hind's Expedition vol. II, p. 82, 1858.
