Seen here are just two examples of the nearly 200 Rodman, Columbiad and the largest (35,000lbs.) and most accurate 300-pound Parrott cannons that were buried with the battery wall during the fort's reconfiguration in 1889. Uncovered in 1968, many of these arms were cleaned and put on display. Then, in the mid 1970s, further excavation was forbidden, hence leaving these cannons in their original resting place as seen in these two photos
