Fort Jefferson

Fort Jefferson Memorial Park features a stone monument marking the location of a former wooden fortification that measured 100 feet on each side. The simple marker commemorates the original structure that stood at this site during early American expansion.

The United States Army built Fort Jefferson in October 1791 during the Northwest Indian War as a supply depot under General Arthur St. Clair's command. The fortification played a role in early military operations to control the territory.

The site marks the meeting point of early American military expansion and Native American territorial disputes in the Northwest Territory during the 1790s. It reflects the complex relationship between settlers and indigenous peoples during this era.

The memorial park can be visited at 3981 Weavers-Fort Jefferson Road near Greenville without admission fees during daylight hours throughout the week. It is best to visit during the day to fully appreciate the monument and surrounding landscape.

The site witnessed the first recorded executions of settlers in Darke County when three soldiers were convicted and hanged following military court-martial. This grim episode reveals the harsh military discipline imposed at this early frontier outpost.
