Fort Zachary Taylor at Key West, Florida
“Construction of the fort began in 1845 as part of a mid-19th century plan to defend the southeast coast through a series of forts. The fort was named for United States President Zachary Taylor in 1850, a few months after President Taylor’s sudden death in office.
Yellow fever epidemics and material shortages slowed construction of the fort, which continued throughout the 1850s. At the outset of the U.S. Civil War in 1861, Union Captain John Milton Brannan seized control of the fort, preventing it from falling into Confederate hands and using it as an outpost to threaten blockade runners.
Originally, the fort was surrounded by water on all sides, with a walkway linking it to the mainland. The fort was completed in 1866, although the upper level of one side was destroyed in 1889 to make way for more modern weapons, with the older cannons being buried within the new outer wall to save on materials. The fort was heavily used again during the 1898 Spanish-American War. ” (wiki)
Fort Zachary Taylor was really interesting, but my favorite part was definitely the iguanas.
