A non-US citizen I am still learning about the Civil War. The Visitor center is a good way of getting to know this more in depth.
The 20 min movie was good and informative. The Cyclorama seemed dated and off-target in comparison. We ended up going after 10 min and went to the museum instead.The museum has many nice exhibits and is divided up over the three days and the aftermath. I would have wished for more on the aftermath and why the battle was so decisive and important for an understanding of the Civil War.
