Johnston's Line Archaeological Site

Johnston's Line Archaeological Site is a Civil War fortification complex along the Chattahoochee River in Cobb County featuring remnants of defensive earthworks and military structures. These elements show how soldiers constructed barriers and strongholds to control movement across the landscape.

The fortification line was constructed in 1864 under General Joseph E. Johnston's orders as Confederate forces faced advancing Union troops during the Atlanta Campaign. This defensive network represented a critical attempt to slow Union advances in the region.

Archaeological investigations at the site have revealed numerous artifacts including musket balls and military equipment that document soldiers' experiences during the conflict.

The site has informational signs and markers positioned throughout that help visitors understand the layout and function of the defensive works. Wear sturdy shoes as you navigate the earthen structures and uneven terrain.

Nine surviving log and earth forts dot the preserved landscape, representing the most complete remaining section of the Chattahoochee River defensive line. Their design reveals how quickly soldiers could construct temporary fortifications using available materials.
