Inscription. These hill-like structures on the terreplein protected ammunition from enemy fire. They also could shield nearby gun crews if necessary. Sixteen traverse magazines are located between gun platforms on the open—and thus vulnerable—top tier of the fort. Plans called for the large detached magazine, with arched roof on the parade ground below, to supply gunpowder for US warships, but that magazine was never completed.

(caption)
These unfinished traverse magazines would have been finished with galvanized iron roofs over wooden beams. The space between the roof and masonry dome would have been filled with sand.

Erected by National Park Service, U.S. Department of the Interior.
