Plum Bayou Mounds Archeological State Park

A National Historic Landmark, the Toltec Mounds site comprises one of the largest and most impressive archeological sites in the Lower Mississippi River Valley. Preserved here are Arkansas's tallest American Indian mounds. Three mounds remain where 18 once stood surrounded by an earthen embankment eight to ten feet in height, a portion of which is still visible today. These ancient earthworks are the remains of the late-Woodland thru early-Mississippian Period ceremonial and governmental complex which was inhabited here from A.D. 650 to 1050. The park visitor center features exhibits including artifacts from the site, an A/V theater, and archeological research laboratory. A meeting room and enclosed pavilion (with restrooms) that overlooks the mounds are available for rent.
