Letchworth Mounds Archaeological State Park is a 188.2 acre[1] Florida State Park that preserves the state's tallest prehistoric, Native American ceremonial earthwork mound, which is 46 feet (14 m) high. It is estimated to have been built 1100 to 1800 years ago. This is one of three major surviving mound complexes in the Florida Panhandle. The people who built the mound are believed to have been members of the Swift Creek Culture, a group of Native Americans who lived in North Florida between 200 and 450 A.D. The hierarchical society planned and constructed massive earthwork mounds as expression of its religious and political system.
The archeological park has exhibits to interpret the artifacts and evidence of nearly 10,000 years of human habitation found at this site. It is located approximately six miles west of Monticello, a half mile south of U.S. 90, in northwestern Florida. The address is 4500 Sunray Road South.
Two related sites in the panhandle are from the later Fort Walton Culture (1100-1550 CE): Fort Walton Mound, a National Historic Landmark; and the Lake Jackson Mounds Archaeological State Park.
