Must-go for any new resident to Charlotte, NC, or even the south in general. I've always enjoyed knowing a little bit about what was there before. It gives you some perspective of where the city is currently and how far they've come.
The New South exhibit was very informative and fun to see the racial history from even less than 20 years ago. The LGBTQ exhibit was quite non-controversial so didn't excite me as much, meh.
Park in the 7th St. garage on Sundays for validated tickets for the day! Free admission then as well but donations accepted.
