There are no right angles, every room flows seamlessly into the next, and the foyer is one of the most stunning of any Smithsonian. Every tribe represented in the museum contributed the artifacts for their specific exhibit, and every tribe named a co-curator to work with Smithsonian staff. What a fantastic collaboration.
Something that stood out to me is that every tribe has an exhibit explaining their creation legend. I like the way the website explains it: "...Native cosmology — the worldviews and philosophies related to the creation and order of the universe — and the spiritual relationship between mankind and the natural world." To be completely honest, so many tribes are represented and while the displays are beautiful they are really text-heavy. Trying to take in all the information is impossible in the time I had, so I got the basic idea and read in detail the legends of only a few tribes.
The most striking exhibit is one discussing the arrival of the Europeans. You leave a room filled with gold and art and relics of thriving, wealthy, self-sufficient tribes...and you turn the corner to walk down a hallway filled with bibles and guns. I think the display speaks for itself. I'm glad they didn't skirt around this issue and I'm glad it makes people uncomfortable. It should.
