Each fort was placed to control river access, defend against rivals, and trade with Indigenous nations across the Hudson Bay watershed.
York Factory - The Principal Depot
At the mouth of the Hayes River, York Factory was the company's main warehouse and administrative center. Built in 1684, it housed up to 300 people in peak season and stored over 75,000 beaver pelts a year.
- • Octagonal wooden palisade (400 feet diameter)
- • Central warehouse (200 x 60 feet)
- • 12 brass cannons on bastions
- • Officer quarters with stone chimneys
Prince of Wales Fort - Stone Citadel
Built between 1731-1771 at the Churchill River's mouth, this stone fortress took 40 years to finish. Its 40-foot-thick walls and position made it the strongest structure in North America's fur trade.
- • Star-shaped design (300 feet per side)
- • Limestone blocks quarried locally
- • 42 cannon emplacements
- • Underground powder magazine
Architectural Plans & Blueprints
Original surveyor drawings and construction plans reveal the sophisticated engineering behind these frontier fortresses.
York Factory Ground Plan (1788)
This detailed survey by company engineer Thomas Thomas shows the complete layout including the Great Hall, factor's residence, carpenter shop, and blacksmith forge. Note the strategic positioning of the powder magazine away from living quarters.
Surveyor: Thomas Thomas
Date: July 1788
Prince of Wales Fort Cross-Section
Engineer Samuel Hearne's detailed elevation shows the impressive 6-foot-thick ramparts and the ingenious drainage system that prevented ice damage. The drawing includes specifications for cannon placement and firing angles.
Engineer: Samuel Hearne
Date: September 1774
Cumberland House Trading Post
The company's first inland post, established in 1774, featured a more modest design suited to the Saskatchewan River location. This plan shows the adaptation of fort architecture for interior trade locations.
Builder: Samuel Hearne
Date: October 1774
Norway House Depot Complex
Located at the northern tip of Lake Winnipeg, Norway House served as the critical junction for brigades traveling between York Factory and western posts. This 1825 plan shows the specialized boat-building facilities.
Architect: John Rowand
Date: May 1825
