 In the past, each country of the European Union had its own money. Today, 19 countries of the Union have the same money, the euro. 338 million Europeans are stronger together with the euro. But who looks after the euro? It's the European Central Bank and the central banks of the euro area countries. They issue euro banknotes. The European Central Bank is located in Frankfurt, Germany. Each country has its own national central bank, usually located in the capital. All the banknotes show windows or doorways on the front and bridges on the back. Some of them are old, some modern.
