The Piqua Historical Area State Memorial 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 United States 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. Preserved and furnished structures include Johnston's two-story mixed Dutch Colonial/Georgian style farmhouse, a unique two-story spring house, and a cider house. Costumed interpreters and craft demonstrators provide farm tours and display activities in the summer kitchen and fruit kiln areas. A mammoth double-penned log barn, constructed in 1808, is reputed to be the oldest and largest of its type in Ohio, and is still in use on the grounds. Nearby a ring-shaped mound earthwork discovered and preserved by Johnston was constructed by people of the Adena culture over 2,000 years ago. 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. In 2001 the museum was renovated with updated exhibits that trace the story of the Eastern Woodland Indians of Ohio and the newly acquired Fort Pickawillany site. Artifacts from Ohio's canal era are also on exhibit. The patio portion of the museum building allows visitors the opportunity to view a restored mile-long section of the Miami and Erie Canal, which extended the length of Ohio from Toledo to Cincinnati. An array of outdoor 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. Afterwards, guests may enjoy a ride aboard the General Harrison of Piqua, a replica 70-foot-long mixed cargo 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.

The site offers exhibits; tours; demonstrations; boat rides; and recreational and educational events, including living history events.

Marietta, Ohio is proud of its riverboat heritage and at the Ohio River Museum visitors can discover the golden age of the steamboat, and learn more about the ecology of the Ohio River system. The Ohio River Museum consists of three exhibit buildings, the first of which houses displays depicting the origins and natural history of the Ohio River. The history of the steamboat on the Ohio River system is featured in the second building, along with a video presentation on river steamboats. The last building features displays about boat building, mussels in the Ohio River system, and tool sand equipment from the steamboat era. Outside the museum, on the Muskingum River, visitors can take an escorted tour of the W.P. Snyder Jr.—the last intact steam-powered "pool-type" stern-wheeled towboat in the United States. Other exhibits on the museum grounds include the pilothouse from the steamboat Tell City as well as a full-scale reproduction of a flatboat from Ohio's early settlement period. Also on site are a series of poles showing the heights of some of the worst floods to hit the area in its recorded history: the 1884 flood at 54.5 feet, the 1898 flood at 49.6 feet, the 1907 flood at 52.1 feet, the flood of 1913 at 60.3 feet, and the 1937 flood at 55 feet.

Iron Mission State Park Museum tells the story of development in Iron County when in the 1850s, Brigham Young sent Mormon missionaries here to mine and process iron. Museum displays include horse-drawn vehicles used from 1850 to 1920 and a collection of pioneer artifacts. An iron industry exhibit features the only known remaining artifact from the original foundry—the town bell. In addition to the permanent collections, changing special exhibits highlight artists from the local region, as well as rarely seen artifacts from the museum's collections. Other items of interest include several historic cabins, a large collection of horse-drawn farm equipment, and a replicated pioneer household. In addition, Iron Mission now manages the historic ruins of Old Iron Town, an iron foundry west of Cedar City that operated in the 1860s—1870s.

In late 1791, Miami Indians defeated General Arthur St. Clair's forces at this site along the Wabash River. Nearly three-quarters of St. Clair's men were killed or wounded in the Indian attack. In late 1793, General Anthony Wayne sent a force to build a four-blockhouse post named Recovery at the site of St. Clair's defeat. It was completed in March of 1794 and on June 30 of that year General Wayne's army defeated a huge Indian force. This set the stage for Wayne's final triumph at Fallen Timbers in August of 1794. Today Fort Recovery State Memorial offers visitors a glimpse of the 1790s, featuring two reconstructed blockhouses with connecting stockade, a monument, and a museum.

The East Liverpool Museum of Ceramics houses an extensive collection of the wares produced by "America's Crockery City." Related displays on the social, political, and economic history of this town show the impact of industry on the community. Ceramic manufacturing was more important in East Liverpool during the late 19th century than is steel production in Pittsburgh or automobile manufacturing in Detroit today. Located in the former city post office, the museum is a graphic example of the adaptive use of old buildings. The exhibits in the museum depict the growth and development of East Liverpool and its ceramic industry from 1840 to 1930, the period when the city's potteries produced over 50% of the ceramics manufactured in the United States. Through the skillful use of photographs, artifacts, and life-size dioramas, the exhibits vividly the products and life of one of Ohio's most unique cities.

The oldest museum in the United States devoted to architecture and design, the Octagon Museum enables the American Architectural Foundation to increase public awareness of the power of architecture and its influence on the quality of life. The building was designed by Dr. William Thornton for Colonel John Tayloe III, and was constructed between 1799 and 1801, and is considered one of the best examples of Federal period architecture in the country. During the most recent restoration, the exterior and interior were restored to reflect the house during the Tayloes' occupancy between 1817 and 1828.
