At one time the Museum of Nature (Ottawa, Canada) was the most surreal experience you could imagine. The building is literally a massive castle. Beautifully built with an atmosphere without comparison. They had the most fantastic paleontology section where you would start at the bottom of a ramp, very dark and foreboding and see fossils from a billion years ago. As you walk up the ramp you see newer and newer fossils - they did an excellent job showing transitional fossils. The ramp would wind around, showing the incredible assortment of life our planet has seen in the past. Finally, it would open up into a large chamber with dinosaur skeletons as far as the eye could see. You would begin with Triassic, Jurassic then Cretaceous. The chamber would then lead to the rise of mammals, ice age, etc... I swear the designer was a genius.
After renovating (I kid you not) they've lumped everything together in a horrible assortment of ice age animals, dinosaurs, mammals, etc... in a set of adjoining open ceiling rooms. There's no atmosphere (everything is bright white with phosphorescent lighting) and the science is certainly gone. I've tried to look into what idiot designed the new layout and I was certain I would find some slack-jawed creationist being responsible but no luck.
Anyway, this is just me venting and telling people not to waste their time on this travesty. However, the three museums of war, aviation and civilization in the Ottawa area are fantastic!
