Fort Jefferson park and monument marks the site of an advance outpost of General Arthur St. Clair, built in October 1791. It was named in honor of Thomas Jefferson, then Secretary of State. One of a chain of defensive forts built to protect army supplies from Indians, it served as a supply base throughout the campaigns of General St. Clair and General Anthony Wayne. It was abandoned in 1796.

The monument is made of faced granite field boulders, six feet square and twenty-feet tall. The area is maintained as a roadside park with a picnic shelter and grills. No part of the fort remains.
History of the Area
Fort Jefferson State Memorial, located in Darke County, Ohio, has a rich and interesting history that dates back to the early 19th century. Here is an overview of its historical significance and development:

1. Establishment: The fort was established by General "Mad" Anthony Wayne in 1793 as part of a chain of military posts intended to maintain American control over the Northwest Territory. It was initially named Fort Deposit and served as a supply depot and base of operations for Wayne's troops during the Indian Wars.

2. Renaming to Fort Jefferson: In 1796, Fort Deposit was renamed Fort Jefferson to honor Thomas Jefferson, who was then serving as Vice President of the United States.

3. Role in the Indian Wars: Fort Jefferson played a crucial role in several conflicts with Native American tribes, including the Battle of Fallen Timbers in 1794. This decisive battle, fought near present-day Toledo, Ohio, resulted in a major American victory and led to the signing of the Treaty of Greenville in 1795, which opened much of present-day Ohio to settlement.

4. Abandonment and Reconstruction: Following the signing of the Treaty of Greenville, Fort Jefferson lost its strategic importance and was subsequently abandoned by the military in 1796. It fell into disrepair over the years until efforts were made to reconstruct it in the early 20th century.

5. Fort Jefferson State Memorial: In 1930, Fort Jefferson was acquired by the state of Ohio and designated as a state memorial. Reconstruction efforts began, and the fort was rebuilt based on original drawings and specifications from the late 18th century.

6. Preservation and Interpretation: Today, Fort Jefferson State Memorial is a historical site that showcases the reconstructed fort and offers visitors a chance to explore the history of the region and the Indian Wars. The site includes a visitor center with exhibits detailing the fort's role in early Ohio history.

Fort Jefferson State Memorial stands as a testament to Ohio's role in early American military operations and offers a glimpse into the challenges faced by the pioneers and soldiers during the Indian Wars of the late 18th century.
