Biblioteca National de Brasilia
Do take the offer of a tour... else you will end up completely baffled (like me).
I have no idea what this building is about.
It is very pretty... but a national library without books? It is all very Zen (well... there are a couple shelves of books but probably less than your local library...)
Location Brasilia, Goias (GO), Brazil, South America
