Aarhus is a city of growth. With a population of more than 300,000, Aarhus is Denmark's second largest city. It is at heart, however, also Denmark’s youngest city when you consider the average age of its habitants which is far lower than anywhere else in the country. At the University of Aarhus alone there are nearly 35,000 students, and there is a total of 25 educational and research institutions in the city. But Aarhus is also a city with clearly visible roots, founded, as it was, by the Vikings in the 8th century.
