The golden carriage in the Palais Liechtenstein’s early-18th-century Garden Palace looks like something right out of a Disney fantasy, and the baroque ceiling frescoes in its lavish Hercules Hall are heavenly. You don’t often hear about the tiny Alpine principality of Liechtenstein, or that its origins can be traced back to Vienna. To this day, the House of Liechtenstein maintains two magnificent residences in the city. Besides the Garden Palace, the neoclassical City Palace has parquet flooring by Thonet, a rococo ballroom, and a collection of neoclassical and Biedermeier pieces. In 2004, the Palais Liechtenstein bought the ebony Badminton Cabinet with pietra dura inlays for $36 million—the most expensive piece of furniture ever sold at auction.
