I have high hopes in Rostock Zoo, they have a few older things,as like as every zoo, but a lot of very good new and old enclosures. The next bigger projekt will be the new apehouse, they plan a new elephant house with a new exhibit,and I think, new bear enclouseres will be build in the next future also, but I guess, they waiting for the death of the old kodiak bear(s)and the male polar bear. The female polar bears are younger and could be send to other zoos during the construction.
