From the Florida State Parks website:
"Located near the mouth of the St. Johns River, this site was an important military position during the Civil War, allowing access to the inland areas of Florida's east coast. There was never an actual fort on Yellow Bluff, but an encampment that was fortified and equipped with large guns for protection. Constructed in 1862, the site was occupied by both Confederate and Union troops during the Civil War and-at its peak-housed over 250 soldiers. The site has a T-shaped earthworks and covers about 1.3 acres. Located on Yellow Bluff peninsula on the north side of the St. Johns River (on New Berlin Road). "
