The best reason to visit the Federal Reserve Bank is the chance to (briefly) ogle at its high-security vault – more than 10,000 tons of gold reserves reside here, 80ft below ground. You’ll only see a small part of that fortune, but signing on to a free tour (the only way down; book several months ahead) is worth the effort.

While you don't need to join a guided tour to browse the bank's interactive museum, which delves into the bank's history and research, you will still need to book a time online. Bring your driver's license or passport.
