Directly across from the Museum of Art History is the Museum of Natural History. The buildings are almost identical. Both have a 200 foot high dome yet slightly different sculptures, friezes and bas reliefs. Children definitely favor the Naturhistorisches Museum Wien. The collection consists of over 20 million items. The 39 exhibition rooms show the evolution of the earth, animals, insects and humans. Displays range from tiny organisms to fossils and gems to giant dinosaur skeletons. You can also explore the universe in the Digital Planetarium plus marvel at a range of meteorites.
