This Impossible Library Seems To Be Upside Down

When I first saw this photo I thought it was really strange. For some reason, my brain didn’t believe it was real. There’s something impossible about it, as if it’s upside down in space. But it’s real.

It’s the Vasconcelos Library, designed by Alberto Kalach architects, a 38,090 square metre steel, concrete and glass leviathan in Mexico DF. [Archdaily]
