Where would you find the World Bank?

Question

I'm going on a Europe trip and it's a huge loss of money to exchange.

Answer 1

If you mean literally the World Bank, it is here:

The World Bank

1818 H Street, NW

Washington, DC 20433 USA

Your question sounds like you are asking where to change money.  Do it at the airport.  It actually has fairly good rates.

If you are asking something else, then please clarify.
