Regensburg is an ancient city in Bavaria. It is one of those few cities left in Germany which is still reasonably intact after a tumultuous 20th century. This city is very beautiful, and definitely worth visiting if you are in this part of the world. I can imagine many sunny summer evenings by the river, drinking beer, listening to live music and watching the boats go by. (At least, that's what I imagined, when I was walking around here in the winter.)
