This is only a very small part of the Alfred-Brehm-House - it is a combined Cat/Bird/Small Mammal house with a large number of not-exactly-huge cat exhibits around its sides, multiple smaller enclosures between the cat indoor exhibits inside and a large, central free-flight bird tropical exhibit (currently undergoing repairs).
My own run through my photos has just reached this house, so the next batch of mine will give some other views of the building.
