Fort St. Pierre Site, Archaeological site in Warren County, Mississippi.

Fort St. Pierre Site is an archaeological site in Warren County, Mississippi, set on a bluff above the Yazoo River. Excavations have exposed the foundations of fortifications and living quarters that researchers use to study early colonial life in the region.

French soldiers established this post in 1719 as the northernmost outpost of French Louisiana. It was destroyed in 1729 during an attack by the Natchez and was never rebuilt.

Native pottery makes up 43% of the artifacts recovered at Fort St. Pierre, and the clay vessels were made mainly by Native women. The fort's residents were Yazoo, Koroa and Ofogoula peoples before the French came; the Yazoo and Koroa took part in the 1729 attack, while the Ofogoula had moved to the Natchez area.

The site sits in a rural part of Warren County and is easiest to reach by personal vehicle. Visiting during drier months makes it easier to walk around the grounds and see the excavated areas.

Excavations at the site turned up Venetian glass beads and European ceramics, showing that this remote post was tied into long-distance trade networks. A fort at the edge of the colonial world was connected to markets on other continents.
