Fort Jefferson on Garden Key in Dry Tortugas National Park in the Gulf of Mexico is built out of sixteen million bricks, some from the Pensacola area, but most from the North, particularly New England, particularly Maine. In the early years of construction, the fort was built by hired laborers (often Irish), engineers, craftsman, and slaves on loan from their owners in Key West. During and after the Civil War, prisoners at the fort, hired laborers, and freed slaves comprised the construction crew.
Construction on the fort began in 1846, the same year that the United States went to war with Mexico, and its location was seen as being key to controlling the Gulf of Mexico. While the fort was being constructed, however, military technology developed for the Crimean War in the mid-1850s called into question the durability of masonry armaments. Then in April 1862, during the Civil War, the United States successfully bombarded and breached Confederate-held Fort Pulaski near Savannah, Georgia, rendering masonry fortifications obsolete. Construction on Fort Jefferson, though, continued until 1875, but the fort remains unfinished.
Now the fort is administered and cared for by the National Park Service. It is a monument to the first half of the nineteenth century, when the Monroe Doctrine of hemispheric hegemony (not to mention the lust of southern slavers to annex Caribbean islands and turn them into slave states) dictated strong U.S. military presence in the Gulf of Mexico.
During the Civil War, the United States held the fort, ensuring that it never fell into traitorous hands, and it became both part of the naval blockade of the South and a military prison. In 1935, Franklin Delano Roosevelt declared it Fort Jefferson National Monument. By 1992, military history had given way to ecology in assessing the Monument’s importance, and Fort Jefferson National Monument became Dry Tortugas National Park. The fort and destroyed Garden Key served as a place to absorb visitors while the other tiny islands and the waters around them healed.
It was the afternoon of November 15, 2016, and with the island drained of its day trippers, our little gang of eight ventured into Fort Jefferson to explore, learn, take in history, and be generally irreverent.
