The Johnston Farm & Indian Agency celebrates 2,000 years of Ohio's rich history from prehistoric Indians to Ohio's canal era. The focal point of the peaceful 200-acre park is John Johnston — farmer, public official, and U.S. Indian Agent for western Ohio from 1812 to 1829. Today, visitors enjoy the home and farm of this most extraordinary man much as it appeared in 1829.

Not far from Johnston's farm is a modern museum, 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. Guests also 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.
