Vienna's astounding Naturhistorisches Museum covers four billion years of natural history in a blink. With its exquisitely stuccoed, frescoed halls and eye-catching cupola, this late-19th-century building is the identical twin of the Kunsthistorisches Museum Vienna opposite. Among its minerals, fossils and dinosaur bones are one-of-a-kind finds like the minuscule 25,000-year-old Venus von Willendorf and a peerless 1100-piece meteorite collection. Panoramic rooftop tours take you onto the building's roof to view the ornate architecture up-close; children under 12 aren't allowed.
