800 Fort Negley Blvd, Nashville, TN 37203

Fort Negley was a fortification built by Union troops after the capture of Nashville, Tennessee during the American Civil War, located approximately 2 miles (3.2 km) south of the city center. It was the largest inland fort built in the United States during the war.  Donelson (on the Tennessee and Cumberland Rivers, respectively), Confederate commanders decided that any further effort in the defense of Nashville would be pointless, and they abandoned any attempt to keep Nashville behind their lines. It was almost immediately occupied by Union forces, who rapidly began preparations for its defense. The largest of the fortifications erected was Fort Negley, a star-shaped limestone block structure atop St. Cloud Hill, south of the city. The construction of the fort was overseen by Captain James St. Clair Morton. The fort was constructed out of 62,500 cubic feet (1,770 m) of stone, 18,000 cubic feet (510 m) of earth and cost $130,000. It was largely constructed using the labor of local slaves (including women), newly freed slaves who had flocked to Nashville once it was taken by Union forces with the understanding that their status as slaves was to be revoked were they to work for the Union, and by free blacks forcibly conscripted for the work. Records show that 2,768 blacks were officially enrolled in its construction. The fort was named for Union Army commander General James S. Negley.

When the Battle of Nashville finally began in December 1864, it was largely fought on the heights even farther south of the city than Fort Negley, which despite its then-impressive appearance never played a leading military role. Shortly after the war, the fort was abandoned and fell into ruin; however, its outline could be readily discerned for many years afterwards in the encroaching woods. During the Reconstruction period, the area was used as a meeting place for the Ku Klux Klan, as confirmed by former Klansman Marcus B. Toney.
