6 Kunsthistorische Museum, Vienna. Expensive admission, but worth it. Some truly great Rubens (Little Fur, Head of Medusa, and others), a very sexy Correggio, and some marvelous imperial gewgaws left over from the Hapsburgs.

7. The Armory, Moscow. Start with a dozen eggs. Faberge eggs, that is. Jeweled crowns by the armload. Gilded carriages, illuminated manuscripts, and jeweled icons. All of this, however, pales in comparison with the contents of the diamond vault. The vault contains piles of diamonds. Big diamonds, small diamonds, cut diamonds, uncut diamonds. Piles of gold bars. Giant gold nuggets. Platinum nuggets the size of basketballs. I like this place.

8. Hermitage Museum, St Petersburg. The Hermitage is such an overwhelming building that the art it contains is almost of secondary interest. The Hermitage was the Winter Palace of the Russian Royal Family, and it shows. After walking up the Jordan Staircase, even Versailles will look squalid. After an hour or so in the jewelry collections, if it isn’t solid gold with diamonds, you won’t even bother to look at it (and you’ll understand why Russia had a revolution). Oh, yeah, a huge collection of Impressionists, seminal works by Rembrandt, a Leonardo, and all the usual suspects.
