The Naturhistorisches Museum in Vienna covers a span of four billion years of natural history and is displayed in a late-19th-century building with elaborately stuccoed and frescoed halls, as well as a cupola. It includes fossils, minerals, dinosaur bones and rare finds such as the 25,000-year-old Venus of Willendorf and a collection of 1100 meteorites. Audio guides can be purchased for €5, and rooftop tours (not open to children under 12) offer views of the ornate architecture.
