3. Federal Reserve Bank of New York
Not all castle architecture in New York City has a Gothic inspiration. The Federal Reserve Bank of New York takes cues from Italian palazzos, like the Medici Riccardi palazzo in Florence with a rusticated lower facade and arched stone windows. Inside, there’s a gold vault containing the world’s largest depository of gold, about 10% of the world’s total. The Fed guards this gold on behalf of other countries, states, residents and more. Recently, Bangladesh accused the Fed of losing $100 million in a possibly questionable bank transfer to the Philippines.
