Fort Pulaski was constructed in the early 1800’s and quickly overtaken by Union technology in 1862 with the advent of rifled cannon. Yet the maintenance still goes on. Thankfully. It is difficult to keep up this brick fort built partially with slave labor bricks from SC and partially from bricks made in the Northeast. The northern bricks were made with different clay and could be hardened. Here a park service maintenance person works to remove some of the old morter preparing the bricks for repointing. When they removed some bricks the ones not seen had finger prints and thumb marks in the bricks, showing the hand labor required. Those bricks were always facing in or covered with a second layer brick.
