St. Petersburg occupies a world of architectural order forged out of a swamp at a forbidding latitude. Peter the Great's invention cost the lives of thousands of workers sent to make the Baltic Sea delta inhabitable 300 years ago. But his vision lives on -- even new buildings adhere to the symmetry and classicism of Peter's day. The sea-green Winter Palace overlooking the Neva River houses the Hermitage Museum's staggering collection of fine art, and sumptuous royal estates dot the surrounding forests. St. Petersburg's reputation as Russia's intellectual and cultural center has not brought the city the prosperity that today's Moscow enjoys, but Petersburg has better hotel choices and a restaurant scene nearly as vibrant as the capital's.
