Lake Jackson Mounds Archaeological State Park (8LE1) is one of the most important archaeological sites in Florida, the capital of chiefdom and ceremonial center of the Fort Walton Culture inhabited from 1050–1500. The complex originally included seven earthwork mounds, a public plaza and numerous individual village residences. One of several major mound sites in the Florida Panhandle, the park is located in northern Tallahassee, on the south shore of Lake Jackson. The complex has been managed as a Florida State Park since 1966. On May 6, 1971, the site was listed on the U.S. National Register of Historic Places as reference number 71000241. Fort Walton culture The site was built and occupied between 1000 and 1500 by people of the Fort Walton culture, the southernmost expression of the Mississippian culture. The scale of the site and the number and size of the mounds indicate that this was the site of a regional chiefdom, and was thus a political and religious center. After the abandonment of the Lake Jackson site the chiefdom seat was moved to Anhaica (rediscovered in 1987 by B. Calvin Jones and located within DeSoto Site Historic State Park), where in 1539 it was visited by the Hernando de Soto entrada, who knew the residents as the historic Muskogean-speaking Apalachee people. Other related Fort Walton sites are located at Velda Mound (also a park), Cayson Mound and Village Site and Yon Mound and Village Site. Site description When the site was abandoned it was a large complex () that included seven platform mounds, six arranged near a plaza and a seventh (Mound 1) located to the north. The mounds were the result of skilled planning, knowledge of soils and organization of numerous laborers over the period of many years. The ceremonial plaza was a large flat area, constructed and leveled for this purpose, where ritual games and gatherings took place. The area around the mounds and plaza had several areas of heavy village habitation with individual residences, where artisans and workers lived. There were also communal agricultural fields in the surrounding countryside, where the people cultivated maize in the rich local soil, the major reason such a dense population and large site were possible. Only a few of the mounds in the park have been systematically excavated by archaeologists. The site itself is oriented on an east–west axis, oriented perpendicular to the north–south axis of the Meginnis Arm,
