Projectiles for U.S. 20-inch Rodman Gun
These thousand pound cast iron balls fit the huge gun in the park just outside the fort’s main gate. The 20-inch model of 1864 was experimental; the largest standard seacoast gun in use during our Civil War was the 15-inch Rodman.
Marker is on Sheridan Loop, on the right when traveling east.
