Historic Hudson's Bay Co. fortified post and the first of the interior forts built by the Company. It was erected to prevent encroachments of the French traders in 1741, on the north shore of the Albany river about 8 miles below the forks of the Kenogami and Albany rivers at the mouth of the Henley river, and about 150 miles up the Albany river. The French had erected a fort within 120 miles of Fort Albany, which later they had abandoned and the Hudson's Bay Co. erected a blockhouse near that place which commands the two branches of the river. It was in operation in 1759. Henry says that the French plundered Henley House in 1760-It was probably destroyed at that time, the French leaving for the seat of war in the east. It was rebuilt in 1764. Was in operation in 1774 and was listed among the Company posts at date of union 1821. It was probably closed soon after 1857 as it does not appear on the 1857 or later lists. Nothing was left of the old fort in 1880. Shown on maps Nos. 1, 3, 8, 12, 19, 24, 79, also 96 Rocque 1763 "an English Factory" & on No. 8 (1857)
