The Globe Museum is one of Vienna's more specialised museum stops, and that is part of its charm. Its collection covers terrestrial and celestial globes, historic maps, and instruments that show how Europeans pictured the world before satellite images made the planet feel familiar.
It is a good short visit if you like old cartography, navigation, or beautiful scientific objects. The museum sits in the Innere Stadt, so it is easy to fold into a walk between larger central sights.
