You don't have to go to Ground Zero in New York to know that the place where the 100- plus-story Twin Towers once stood is a haunting place. But have you ever wondered what happened to the steel that once stood in that very place?

As it turns out, 7 3/4 tons of steel were taken from the rubble where the towers once stood. They were shipped to Louisiana, where they were melted down and repurposed into what is now the USS New York, an official vessel with the United States Navy. You can find the steel from the World Trade Center towers at the bow of the ship -- the nose -- which is the part that cuts through the water.
