History buffs should seek out this fascinating but little-visited collection. Here the full panorama of Old Vienna’s history unfolds, beginning with the settlement of prehistoric tribes in the Danube basin. Roman relics, artifacts from the reign of the dukes of Babenberg, and a wealth of leftovers from the Habsburg sovereignty are on display, as well as arms and armor from various eras. A scale model shows Vienna as it looked in the Habsburg heyday. You’ll see pottery and ceramics dating from the Roman era, 14th-century stained-glass windows, mementos of the Turkish sieges of 1529 and 1683, and Biedermeier furniture. There’s also a section on Vienna’s Art Nouveau.
