The only thing I managed to photograph was this stunning piece entitled "Allies in War, Partners in Peace" by Edward Hlavka. This 19.5-foot bronze statue depicts the alliance between the Oneida people and the United States and features General George Washington, Polly Cooper and Oneida Chief Oskanondohna. Truly splendid.
To view a much better photograph of this statue, visit this Smithsonian page.
The most impressive thing of all? The exterior of the building. I'm not usually a big fan of modern architecture but this building simply feels... well... organic. The curves connote water and rolling hills and the stone tiers echo prehistoric rock formations. Just beautiful. A number of Native Americans designed and architected this museum as detailed by About.com:Architecture:
If you ever find yourself in DC, it's definitely worth a visit - even if you only get to see the exterior. And if you do wander inside, check out the movie in the Rasmusen Theater on the fourth floor. It's truly a unique experience.
