I usually limit my trip reports to locations outside the Blue Book canon, mainly because others have done a thorough job already, but also to raise awareness of other worthy destinations. I'm pretty sure both Leipzig and Erfurt are in the books, but they're rarely mentioned in the chatter on this website. So, here goes my attempt at describing them.
I passed through Leipzig for the first time about two months ago on my way to Rügen, and I instantly could see that this city deserved a more thorough investigation than a one night stop-over. Hence, Leipzig Part II. As I saw earlier, Leipzig is a suprisingly vibrant and very attractive city. For centuries, it was the commerical capital of Saxony (while Dresden was the political capital), and the influence still shows. This isn't a city of museums, but a city of shops and banks. Most of the old center contains various high-end stores, offices, restaurants, part of the university, hotels, banks and all the other signs of an economically vibrant city. Architecture-wise, most of the city, inside the old ring and outside, seems to date largely from the Gründerzeit era of the German Empire and post-reunification, with very few of the Plattenbau monstrosities that scar large parts of Dresden, Chemnitz, Jena and east Berlin. Although it doesn't contain anything quite so impressive as Dresden's rebuilt Neumarkt area, overall, I would rate this as the most attractive large city of the former DDR. Walking and driving around the city, you would never know the communist period happened without digging a little deeper.
Probably the most impressive attraction in the city is Leipzig's amazing zoo. Although the menagerie on display probably doesn't contain any animals that you can't see in a zoo in your home state, the design is what sets this zoo apart. The level of detail in the themeing reminds me of Disney's Animal Kingdom, but without rides. The highlight is a gigantic indoor rain forest called Gondwanaland. It's so big it took me about 45 minutes to walk through. In one section, you can even walk among free-roaming squirrel monkeys. I thought "Germans don't wear deoderant" was one of those tired stereotypes that refuses to die despite all evidence to the contrary... but after walking through this rather warm and humid enclosure for nearly an hour, lets just say I was happy for some fresh air. Another bonus about the zoo- almost all of it sits under a thick canopy of vegetation. On the rather warm day I visited, this was much appreciated. (cont.)
