Frogmore Mound Site

Frogmore Mound Site is an archaeological site in Concordia Parish, a rectangular earthen mound roughly 160 by 190 feet at its base and about 14 feet high. The flat top measures around 60 by 70 feet and marks where structures once stood on the summit.

A circular ceremonial structure beneath the mound was built between 1020 and 1260 and shows evidence of being intentionally burned before soil was placed over it. This burning marks a deliberate change in how the site was used.

The site reflects how people in this region lived during the Late Coles Creek period, when communities established settlements along the river. The pottery and objects discovered here tell us about daily activities and connections to the landscape.

The site sits along US Highway 84 with roadside markers that make it easy to locate from the road. A short drive west from Ferriday or east from Jonesville will bring you there without difficulty.

The mound was built using layers of sandy and clay materials carefully placed together. Alongside it lay a village area with pottery fragments and other debris that mark where people once lived.
