Fort Koshkonong

Fort Koshkonong was a military installation from 1832 positioned on the Rock River's banks with wooden walls and corner blockhouses for protection. The structure provided shelter for stationed troops during operations in this region.

The fort was established in 1832 during the Black Hawk War, an escalating confrontation between US forces and the Sauk. Once this conflict ended, the installation was abandoned in 1839 and ceased serving military purposes.

The fort was a flashpoint where European settlers and Sauk and Fox nations clashed, fundamentally changing the region's trajectory. You can sense at this location how two worlds collided and reshaped each other.

A monument from 1907 erected by the Daughters of the American Revolution marks the original fort location for modern visitors. The site is straightforward to locate and provides a good starting point for understanding the area's military history.

After abandonment, the fort's wooden structures were systematically dismantled by local settlers for reuse. This scavenging meant that almost nothing physical remained of the structure by 1840.
