Characteristics

Description

Garden Key is the site of historic Fort Jefferson National Monument, a hexagonal structure with walls 425 feet long rising from a surrounding moat.

In 1846, the US Army began to construct a massive fortification on the tiny island known as Garden Key. Sixteen million bricks were transported via ships to create a massive six-sided, three-tiered fort. t was the biggest coastal fortification in masonry structure in the Western Hemisphere.

Fort Jefferson provided little strategic value during the Civil War and was soon converted into a military prison. By the end of the nineteenth century, it was largely abandoned and allowed to fall into disrepair.
In 1935, Fort Jefferson was designated a National Monument: and in 1992, all of the Dry Tortugas including Fort Jefferson were made a National Park.

The S and N of the three wharves on the E side of the key are in ruins. The center wharf, off the SE front of the fort, is in good condition, with 16 to 22 feet alongside. No fuel, provisions, or water are available.
The National Park Service permits berthing for a maximum of 2 hours.

The mean range of tide at Garden Key is 1.1 feet.

Garden Key est le site historique du Fort Jefferson National Monument, une structure hexagonale avec des murs de 127,5 m de long, entourés d'une douve.

En 1846, l'armée des US a construit une fortification massive sur la petit île appelée Garden Key. Seize million de briques y ont été transportées par bateau pour construire les six murs du fort à trois gradins. C' est la plus large fortification maritime d' Amérique du Nord et la plus grande structure de maçonnerie de l' hémisphère W.

Le fort Jefferson était de petite importance stratégique durant la guerre civile et fût convertie en prison militaire peu après. A la fin du 19ième siècle il fût abandonné et déprécié. En 1935, le fort
Jefferson fût déclaré comme monument national: et en 1992, tout Dry
Tortugas ainsi que le fort Jefferson devinrent un parc national.
