Vienna

Circle the grand boulevard the Emperor built to replace medieval walls. Every building tells a different century's story, from Gothic city hall to Greek parliament, with the Habsburgs' 2,600-room palace anchoring it all.

Klimt's golden kiss, Schiele's raw nudes, a Baroque riding school, and a market where Turkish spices meet Viennese Sachertorte. Art and appetite intertwine on every block.

Descend into catacombs holding Habsburg intestines, sip coffee where Trotsky plotted revolution, and walk streets that Mozart, Freud, and Beethoven all called home. Vienna's old city is Europe's most cultured square kilometer.
