If any city in Germany encapsulates the spirit of the country, it is Heidelberg. Scores of poets and composers—virtually the entire 19th-century German Romantic movement—have sung its praises. Goethe and Mark Twain both fell in love here: the German writer with a beautiful young woman, the American author with the city itself. Sigmund Romberg set his operetta The Student Prince in the city; Carl Maria von Weber wrote
his lushly Romantic opera Der Freischütz here. Composer Robert Schumann was a student at the university. The campaign these artists waged on behalf of the town has been astoundingly successful. Heidelberg's fame is out of all proportion to its size (population 140,000); more than 3½ million visitors crowd its streets every year.
Heidelberg was the political center of the Lower Palatinate. At the end of the Thirty Years' War (1618–48), the elector Carl Ludwig married his daughter to the brother of Louis XIV in the hope of bringing peace to the Rhineland. But when the elector's son died without an heir, Louis XIV used the marriage alliance as an excuse to claim Heidelberg, and in 1689 the town was sacked and laid to waste. Four years later he sacked the town again. From its ashes arose what you see today: a baroque town built on Gothic foundations, with narrow, twisting streets and alleyways.
Above all, Heidelberg is a university town, with students making up some 20% of its population. And a youthful spirit is felt in the lively restaurants and pubs of the Altstadt (Old Town). In 1930 the university was expanded, and its buildings now dot the entire landscape of Heidelberg and neighboring suburbs. Modern Heidelberg changed as U.S. Army barracks and industrial development stretched into the suburbs, but the old heart of the city remains intact, exuding the spirit of romantic Germany.
