You can visit my old home if you ever happen to be in the Groton, Connecticut area. Nautilus is still in the water, in the James River, tied to a pier just outside the submarine base, located one and a half miles off I-95
Nautilus became the second US ship in history to be designated "Historic." The first was the USS Constitution, known as "Old Ironsides,) permanently berthed in Boston, Massachusetts.
Here is a picture of the grand lady tied to the pier
