James A. Garfield National Historic Site preserves the property associated with the 20th President of the United States. Garfield acquired the home in 1876 to accommodate his large family. The home, named Lawnfield by reporters, was the site of the first successful front porch campaign in 1880. James A. Garfield was President from March 4, 1881 until his death on September 19, 1881. Four years after his assassination, the Memorial Library wing was added by Mrs. Garfield and her family - setting the precedence for presidential libraries.

The William Howard Taft National Historic Site commemorates the only man to serve as President and Chief Justice of the United States. The house that Taft was born in has been restored to its original appearance. A visit to the site includes a tour of the restored birthplace and four period rooms that reflect the family life during Taft's boyhood. The home also includes second floor exhibits highlighting Taft's life and career. The Taft Education Center, located adjacent to the Birthplace, houses an orientation video, exhibits on later generations of the Taft family, and classrooms for visiting schools. The signature exhibit of the center is an animatronic figure of the President's Son, Charlie Taft. Charlie tells stories about different family members.

From about 200 BC to AD 500, the Ohio River Valley was a focal point of the prehistoric Hopewell culture. The term Hopewell describes a broad network of beliefs and practices among different Native American groups over a large portion of eastern North America. The culture is characterized by the construction of enclosures made of earthen walls, often built in geometric patterns, and mounds of various shapes. Visible remnants of Hopewell culture are concentrated in the Scioto River valley near present-day Chillicothe, Ohio. The most striking Hopewell sites contain earthworks in the form of squares, circles, and other geometric shapes. Many of these sites were built to a monumental scale, with earthen walls up to 12 feet high outlining geometric figures more than 1000 feet across. Conical and loaf-shaped earthen mounds up to 30 feet high are often found in association with the geometric earthworks. The park contains nationally significant archeological resources including large earthwork and mound complexes that provide an insight into the social, ceremonial, political, and economic life of the Hopewell people. The park visitor center features museum exhibits, an orientation film, book sales area, and self-guided and guided tours.
