Inside the walls of Fort Moultrie, visitors can explore a World War II era harbor defense structure. The joint Army-Navy installation was known as the Harbor Entrance Control Post - Harbor Defense Command Post (HECP-HDCP). Construction of the permanent concrete structure finished in March 1944, which replaced a temporary timber frame structure on the northwest bastion.
The structure has three floors. On the ground floor, the offices housed the Duty Officers and Operations Room and the Message Center, while on the opposite side of the corridor were the HECP and Radio Rooms, Air Conditioning and CWS Room, and Heater Room. The second floor housed the Observation Post, and the Signal Tower was on the third floor.
The missions of the structure were: to protect the harbor facilities and shipping from naval gunfire in event of enemy surface attack; to deny to enemy shipping access to the harbor; to support defense against an amphibious attack.
