Fort Oswego

Fort Oswego is a stone fortification located at the mouth of the Oswego River in New York, featuring pentagonal walls with five bastions positioned to overlook the southern shore of Lake Ontario. The site displays typical features of an 18th-century military installation with visible earthworks and masonry structures.

The installation was established in 1727 as a British military post on the Great Lakes. French forces captured and destroyed it in 1756, marking a significant shift in colonial control of the region.

The fort established a permanent British military presence on the Great Lakes, influencing trade relations between European settlers and Native American tribes.

The site sits at the intersection of West First Street and Lake Street in Oswego and is marked by interpretive signage throughout. Visitors can walk the grounds independently and view the remains of the former fortification.

The installation originally consisted of separate stone structures including a blockhouse called Fort Burnet and triangular stone walls known as Fort Pepperrell. These different components were added in stages as the British expanded the position over time.
