The Albertina in Vienna sits at a corner of the Hofburg palace complex, perched on one of the eleven bastions of the city's medieval wall. To enter, you climb steps or an escalator. That slight elevation isn't architectural whimsy; the museum is sitting on a fortification.

The building was constructed in the 1750s by Albert of Saxony-Teschen as a gift for his Habsburg wife, Marie Christina, and bears a contraction of both their names. Albert assembled one of history's great print collections during his time governing the Habsburg Netherlands, gathering Rembrandts, Rubenses and Dürers, though nearly a third sank in the English Channel during transport. His collection's founding date, 4 July 1776, means the Albertina is exactly as old as the United States.

VoiceMap's self-guided audio tours weave the Albertina into Vienna's Habsburg story, tracing how a man who married into the dynasty built something that outlasted the empire entirely.
