    The revolving gun turret is the most famous feature of the USS Monitor. While the ship's designer, John Ericsson, was not the first to envision a revolving turret, his design for the Monitor was the first completed turreted naval vessel to be built.

    The turret was 21 1/2 feet in diameter and nine feet tall. It was constructed of eight one-inch-thick iron plates that, with the exception of the first two layers, were bolted together so that they could be easily replaced if needed. It weighed about 120 tons and was able to rotate with the help of two steam engines that used a crank to turn four gears.

    The position and shape of the turret on the Monitor led to it being referred to as a "cheesebox on a raft”.
