Sixteen men were lost when the USS Monitor went down in a storm off Cape Hatteras on Dec. 31, 1862, while it was being towed. The sunken ship was discovered in 1974 resting upside down on the ocean floor in about 235 feet (71 meters) of water; efforts to salvage artifacts from the site began in 1998.
Here, a line engraving, published in "Harper's Weekly", 1862, depicting the ship "Ready for Action" after her pilothouse was modified with angled armor plating around its sides.

This view looks forward from the port quarter, with the port side blower hatch in the foreground, the two smokestacks in the middle distance and the turret beyond. The sailor standing atop the turret is holding a telescope.
A photo from July of 1862. On the deck of the USS Monitor, looking forward on the starboard side. The large dents in the gun turret's armor are scars from Confederate heavy guns. The Monitor was a low-lying, floating fortress. Only about 18 inches of the ship appeared above the waterline.
Still upside down, the engine is lifted from the Atlantic in 2001. It was built chiefly from wrought iron, cast iron and copper alloy.

The Brooklyn-built USS Monitor was famous for fighting the CSS Virginia in the Battle of Hampton Roads on March 9, 1862. Although the battle was a draw, it preserved the Union blockade of the Norfolk-area. It also was the first battle between two ironclad warships, marking a turning point in naval history.
Here, a lithograph by Closson Blake, after a painting by W.F. Halsall, depicting the two ironclads engaging at close range.
