Berlin is the largest city in Germany and has a population of 4.5 million. It is the capital city in Germany.
Berlin is best known for its historical associations as the German capital, for its internationality and tolerance, for its lively nightlife, for its many cafes, clubs, and bars, for its street art, and for its numerous museums, palaces, and other sites of historic interest.
Berlin is a relatively young city by European standards, dating to the thirteenth century, and it has always had a reputation as a place filled with people from elsewhere. Someone who has lived in Berlin for ten years will see themselves as a "true Berliner," looking down on the person who has been there for only five. It may seem tough to find someone born and raised here! This is part of Berlin's charm: it never gets stuck in a rut.
German is of course the main language in Berlin but you can easily find information in English and sometimes in French.
The public transport system (U, S-Bahn, bus, tram) uses a common ticket.
