Dancing House, Czech Republic:
Designed by architect Vlado Miluni, this weirdly crooked building was originally named Fred and Ginger after two famous dancers. The site previously had a house of historic significance that was destroyed during the bombing in Prague. 

National Centre for the Performing Arts, China: 
Shaped like a semi-spherical hub, the entire dome is covered with titanium-accented glass. Its construction started in 2001 and it took six years to complete. 46.28 meters in height, it was designed by Paul Andreu. 

Kansas City Public Library: 
A library designed in the form of a stack of books; what else would a library be designed as? Straight out of Kansas City, it was established in 1873 and it looks beautiful.
