Very historic. There are three available tours; the pedestal tour is extra but you can tour the grounds (audio tour included) and the museum. The line took forever to get through, though. Close to 2 1/2 hours. I have been to Pearl Harbor, the Mighty Mo, Space Needle, Yosemite and Mount Rushmore and never had to wait this long (Mount Rushmore was 4th of July, too.) And the airport style security is pretty crazy, so careful what you bring!
