Heidelberg

Heidelberg, known for its famous castle, also boasts Germany’s oldest university plus history-laden lanes in its old town quarter. These attributes are responsible for its “romantic town” label. But these attractions are only a few of the reasons that the city is able to welcome around 3.5 million visitors each year, many of which come for professional reasons. The city also prides itself for its modern scientific and economic location of international repute. Heidelberg lies on the River Neckar and is located in the densely populated region know as the Rhine-Neckar-Triangle.
The greater part of its economy is provided by service industries, including tourism. 
The programme of events held in the city is wide ranging and includes the Ball of the Vampires, (German carnival equivalent) in February, the Heidelberger Frühling Classic Music Festival and the international Easter egg market in spring, the Heidelberger Castle Festival (Student Prince and others) in summer, the Old Town Autumn Festival and the Christmas Market. 
The Heidelberg folk certainly know how to celebrate – whatever the time of year.
