Last but not least, when I saw photos of the Biblioteca Vasconcelos, I had to see this incredible building for myself in-person.

I made the mistake of walking there (don't do that, it's a long walk, and the library is right next to a busy bus station), but the interior of this hulking concrete megastructure will take your breath away.

You fully expect it to start moving, shifting and blending a la Inception:

It's amazing.
