1. South Carolina Department of Natural Resources:The History of Fort Johnson. During early 1861, South Carolina state troops erected two 10-inch mortar batteries of two mortars each and an earthwork of three guns. The signal shot which opened the bombardment of Fort Sumter and marked the beginning of the American Civil War was fired from the east mortar battery on April 12, 1861.

9. Powder magazine
This 18th century powder magazine was discovered in the 20th century after spending about 200 years underground. The fort that once stood here covered this magazine with earth to protect it from shelling, and when that got covered up, people forgot about the magazine underneath. It was found during construction and has been preserved. Workers and students at Grice Marine lab park all around it.

10. Powder Magazine
National Register of Historic Places:
Fort Johnson/Powder Magazine *** (added 1972 - Site - #72001197) Fort Johnson is significant both militarily and politically, especially as the site of the first raising of the South Carolina flag in 1775 and as the site of the first shots fired upon Fort Sumter in 1861. Of the fort itself, only considerably eroded
Confederate earthworks remain, although other elements of the forts foundations are discernable from ground swells and rubble. Fort Johnson was one of the first defensive works constructed to protect the harbor or Charleston against naval attack. The initial fortification was constructed by the British during the years 1704-08 for defense against the
French fleet during Queen Annes War. The fort was named for Sir Nathaniel Johnson, Proprietary Governor of the Carolinas from 1703 to 1709. There was continual reconstruction of the fort from 1704 to 1865, due primarily to damage incurred by storms and to ever-changing military situations. Although the fort itself is in ruins, the powder magazine,
erected in 1765, is intact.

11. Powder Magazine
The powder magazine was buried until 1961; this fact probably saved the building from destruction (the magazine was buried during the Civil War by Confederate soldiers). The building is 27 feet long and 20 feet wide, constructed of brick in Flemish bond, and was originally whitewashed. The front and rear gables are high, with one-dimensional linear extension at their bases on the roofline; the roof is covered with a cement-like coating to prevent it from taking fire. While the exterior is original, the interior is barrel vaulted, probably by the Confederate forces during the early 1860s, to enable the roof to withstand the pressure of the earth when the building was buried.
