Arctic Encounters
I'm guessing most people are familiar with the famous African Panorama at the Tierpark, this is the arctic one. It is complete with polar bear, reindeer, seals (not shown) and eskimos.
The Mappin Terraces at London Zoo (Now re-named Bear Mountain). It contains Sloth Bears and a troop of Hanuman Langurs.
Edit: the bears have now left and will be replaced by australian fauna.
