Hands down one of the most awesome natural history museums ever. EVER! The design and layout of the exhibits is incredible - it's so upscale, yet so... jam packed with science. It's like walking through a palace (which it probably was) but finding it decorated with... natural history. If you're only going to have time to see one museum in Vienna, see this one. Even for their sense of humor along - seriously, I've never seen a museum be so clever and funny in their exhibits. And consider: I'm saying this as someone who studied art history.
