In the late 1800s, this busy river port on the Black River was the shipping point for a large territory. In 1888, a Victorian courthouse was built here. Restored in 1970 to the architect's original plans, the courthouse today serves as a regional archive that contains some of the oldest records in Arkansas. Visitors can tour the Powhatan Courthouse, 1873 Powhatan Jail, 1840s Ficklin-Imboden House, 1888 Telephone Exchange Building, and 1880s Powhatan Male and Female Academy, a unique two-room schoolhouse, all gracing their original foundations.

The site offers tours, exhibits, and workshops.

The Theodore Roosevelt Inaugural National Historic Site is the site upon which Theodore Roosevelt was inaugurated as the nation's 26th president following the 1901 assassination of former president William McKinley. The site is notable as it is the location of one of very few inaugurations that was not performed in Washington, D.C. The location was the home of Ansley Wilcox, a friend of Theodore Roosevelt's. At the home, visitors can learn more about Theodore Roosevelt's past and his tenure as President of the United States.

The site offers detailed historic information, visitor information, an events calendar, and a section for educators with suggested reading material and information on the educational events offered by the national historic site.

Fort Smith National Historic Site encompasses the remains of two forts, as well as the Federal Court for the Western District of Arkansas, the circa 1838 Commissary Building, and a reconstructed gallows. The original fort, Fort Smith, was in use between 1817 and 1824. The Commissary Building supplied food to troops stationed at the fort, and is currently furnished to its 1850s appearance. The visitor's center, located within the historic barracks, courthouse, and jail, contains the courtroom of Judge Parker and exhibits on the Trail of Tears, the federal court, and the military. The Cherokee, Choctaw, Chickasaw, Muscogee Creek, and Seminole walked the Trail of Tears from their ancestral homelands to Indian Territory, an area defined by the U.S. government. The fort served as training grounds for both Mexican War and Civil War soldiers. By 1872, the military compound was transformed into a courthouse and jail. It continued to function as such until 1896. Judge Isaac Parker (1838-1896) is the most famous of the judges who served at this courthouse. Known as the "Hanging Judge," during his 21 years at the fort Parker ordered the execution of 160 men. All of these convictions were for rape or murder, both of which, in the period following the Civil War, were federally required to be punished by death. Many of these cases involved acts of violence between European Americans and Native Americans. The site collections include over 225,000 artifacts.

The visitor's center offers exhibits, films, and period rooms. The Commissary Building offers period rooms. The site offers a walking trail with wayside exhibits on the Trail of Tears, Junior Ranger activities, educational programs, anniversary lectures on punishment and specific executions, in-service educator workshops, and outreach presentations. Reservations and at least two weeks notice is required for school groups. The website offers historic images, an interactive panoramic photograph, a webcam, an artifact of the month, a pre-visit PowerPoint presentation, teaching modules, lesson plans, videos for rental, photograph exhibits for rental, and word searches.

Federal Hall National Memorial is the site where George Washington took the oath of office as the first U.S. President, as well as the site of the first Congress, Supreme Court, and Executive Branch offices.

Now, the building serves as a museum and memorial to the first President and the beginnings of the United States of America.
