Fort St. Joseph

Fort St. Joseph is an archaeological site on an island in Ontario where the remains of an early 19th-century British military installation are visible. Excavations have uncovered the foundations of various structures including a blockhouse, powder storage, residential buildings, and support facilities arranged within a wooden palisade.

The British built this fort in 1796 after a peace treaty moved their original position to American territory, making a new location on the island necessary. It later served as a starting base for military operations before being abandoned.

The site reveals how soldiers, traders, and Indigenous peoples shared daily life and work within the same fortified space. The archaeological findings show a community where different groups coexisted and interacted rather than remaining separate.

The site is best visited during warmer months when it opens to the public and guided tours are available. Established paths lead through the archaeological remains and are easy to follow for most visitors.

This location was the starting point for Canada's only amphibious military assault during the War of 1812, which resulted in recapturing a neighboring fort. This military operation remains relatively unknown to most visitors despite its importance to Canadian military history.
