The museum, some '400 paces' from Johnston's farm as John Johnston recorded, is a modern building, which was constructed to resemble the blockhouse style of Fort Piqua, General Anthony Wayne's 18th-century supply post.
Exhibits trace the story of the Eastern Woodland Indians of Ohio and the Pickawillany village site.
Inside, interpretive panels explore Johnston's later role as a state canal commissioner and provide an introduction to how canals helped in the development and expansion of frontier Ohio.
In the Canal Room, guests learn about the significance of the Ohio Canal system and can view a restored section of the historic Miami and Erie Canal down below. It is on this 1.5 mile section of canal that folks can take a ride on the General Harrison canal boat - guided by costumed staff and pulled by mules.
Guests may enjoy a ride aboard the General Harrison of Piqua, a replica 70-foot-long canal boat often used for transportation of passengers and cargo in the 19th century. Costumed guides direct the mule-drawn boat to provide an authentic and memorable experience for all.
Restroom facilities and a gift shop are located in the museum.
"On the ground stood one of General Wayne's Forts...after the troops were withdrawn the buildings, pickets and blockhouses were left intact. ...the military had 40 or 50 acres under cultivation and under good fence..."
Letter by John Johnston, 1858
