After Leipzig I went to Heidelberg, where I stayed for 2 weeks doing a "Sprachenkurs" with the Goethe-Institut. If you are in any doubt about where to go in Germany, I would recommend Heidelberg immediately - perhaps just obscure enough not to be an obvious tourist destination, yet known to Brits and others enough that it is full to bursting with around 40,000 students of every nationality, it is an absolute dream - one of the oldest surviving German cities (escaping WWII bombing through fortuitous events nobody quite understands, but they may have involved fog that particular night), it boasts a majestic Schloss that you would barely know is ruined until closer inspection, so impressively intact is its infrastructure; a number of wonderful churches; a charmingly restored old bridge; and a beautiful Altstadt/Old Town that is the city's life and soul. Oh, and a golden ape holding a mirror - more on that later.
Nibelungenlied, on why nobody is called Siegfried any more because of its associations with nationalist undertones, on Wagner, and on what a hero really is. Not a bad way to begin!
More anon, as I return to Bavaria!
