Statement of Significance (as of designation - September 14, 1993):
Anna Site is a major prehistoric culture ceremonial center. Construction of the ceremonial mound complex at the site coincides with the florescence of the Plaquemine culture (c. 1200), which formed when the indigenous cultures of the Lower and Middle Mississippi River Valley began to interact. This is the type site of the Anna phase of the Plaquemine culture and contains eight truncated pyramidal platform mounds. Occupation of this site ended around 1500.
