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.
John Johnston's three story Federal farmhouse (including a winter kitchen and office level set below ground) was a unique structure on the Ohio frontier, acting as both a family home and the only Federal Indian Agency in the state.
With the intention of becoming a "gentleman farmer," John Johnston began development of his Upper Piqua farm in 1808 with a two-story log cabin and one of his "other buildings," this double pen log barn.
Down the hill and toward the river from the Johnston's brick house lies a two story spring house. Built between 1808 and 1815, this large structure was a center of activity.
This recreation of the Johnston's 1828 Cider House brings to mind cool autumn afternoons when the frontier family would gather together to peel and process apples to create products that would prove invaluable to them throughout the year.
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.
The Adena mound and earth work found on the Johnston Farm was preserved for the future by John Johnston's care and compassion, and can still be seen today.
