Bombproof
Two bombproofs, each measuring 200 feet long by 12.5 feet wide, were located in the center of Fort Ward. During normal operations, the bombproofs were used as meeting rooms, storage facilities, and sometimes as a prison. In the event of an attack, the structures provided temporary protection for the soldiers. Water was supplied by a well located between the bombproofs.

The roof of a bombproof was constructed from logs that projected three feet over the entrance to the structure, forming a platform (banquette) on which infantrymen could stand to fire their muskets if the fort walls were scaled by an attacker. (The image depicts a cross section of the bombproof showing the earthen roof that provided protection for the shelter below and a platform behind the roof.)
