Fort Jefferson – Florida, USA – In left fortress-reserve
Fort Jefferson – On the Florida Keys, it was supposed to be a fortress for eternity, but life verified these bold plans. It gave shelter to soldiers for only a few years. This is one of the most ambitious construction projects in US history: thousands of workers worked on the Garden Key island. Who used nearly 16 million bricks for nearly 30 years to build the largest fort on the American coast. It was built on a hexagon plan, its walls were 14 m high, and the space in it was enough for: 450 cannons, 1500 soldiers.
The problem was that the fortress was named after President Thomas Jefferson. Most of the time it was simply unnecessary. That is why the government began to use it as a place of isolation for political prisoners in the Civil War. That was until 1867.
When an epidemic of yellow fever broke out in the fort. One of her first victims was a prison doctor. So, to stop the rampant disease, he began, Dr. Samuel Mudd – serving life imprisonment for participating in the plot for the life of Abraham Lincoln. He succeeded: he saved hundreds of prisoners and guards. Mudd was pardoned and the prison was soon closed.
