With a population of 3.4 million, Berlin is not only the capital of Germany, it is also the country's largest city. Covering a total area of 892 square kilometres, Berlin is also the fifth largest city in the European Union. Berlin is an impressive city, thanks to its history and architecture, its wide range of cultural attractions appealing to both young and old alike as well as its dynamic, multi-faceted atmosphere. But there is more to the city than countless sights and attractions. The rivers Havel and Spree along with various lakes and countless forests and parks make Berlin one of the greenest cities in Germany. In recent years, Berlin has joined London, Paris and Rome as one of the most popular travel destinations in Europe.
