The 9/11 Memorial Museum in New York City is easily the most powerful exhibit experience I’ve ever seen. Even the $24 admission fee and long lines are easily forgotten once you enter the museum. The site planning, architecture, and exhibit design is brilliant. Largely underground (four stories deep), the 110,000-sq.-ft. exhibition space elegantly tells the before, during, and after stories of the September 11, 2001 attacks. If you only see one thing while visiting the Big Apple, this should be it.
