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 Park preserves and interprets the Parkin site on the St. Francis River where a 17-acre Mississippi Period American Indian village was located from A.D. 1000 to 1550. A large platform mound on the river bank remains. There were once many archaeological sites similar to Parkin throughout this region, but they did not survive as eastern Arkansas was settled. Visitors can watch research in progress, and see firsthand the results of careful excavations and laboratory analysis. Along with including an archaeological research laboratory, the park visitor center includes an interpretive exhibit area and auditorium. The park interpretive staff offers audiovisual programs, site tours, workshops, and other educational programs and special events and activities. When archaeological excavations are underway, visitors on guided tours can observe them. Visitors experiencing Parkin Archeological State Park can also tour the circa 1910 Northern Ohio Schoolhouse. By the beginning of World War II, there were 15 one-room and two-room schoolhouses providing education for children in Parkin, a town of less than 2,000 citizens. Today, the Northern Ohio School is the only one of these early Parkin structures still standing. The stories it tells of what took place here in the early 20th century in and around the Sawdust Hill community are parts of the historic fabric of Parkin, just as is the park’s interpretation of the prehistoric village of Casqui.

The site offers exhibits, tours, workshops, and educational and recreational programs and events.

Boston African American National Historic Site is comprised of the largest area of pre-Civil War black-owned structures in the U.S. It has roughly two dozen sites on the north face of Beacon Hill. These historic buildings were homes, businesses, schools, and churches of a thriving black community that, in the face of great opposition, fought the forces of slavery and inequality.
