1. Denver International Airport
You wouldn’t think that this picturesque tipi dwelling against a mountain range would be anywhere close to the US – but it’s right in Denver! The peaks glow against the Rockies for an unbeatable sight, and looks more like a remote village than a manmade piece (which it is, by architect Curtis Fentress). In reality, its white Teflon-coated fiber glass meant to imitate the mountain range. Trippy.
