ROM

Royal Ontario Museum is inside of the the coolest crystal's ever seen. Well, this is how the new entrance opened in 2007. It was designed by a Polish-Jewish descent Daniel Libeskind, who is American, but born in Lodź in Poland. You can just lose yourself while being in front of the house, all that glass and all reflections - just wild! The massive doors are quite cool, too. What is inside, I mean in the exposition rooms, have not been discovered yet.
