Leipzig's Max Planck Institute of Evolutionary Anthropology is a striking edifice.
Set among the drab housing blocks of former East Germany, the building, erected in 2003 and made largely of glass, curves gently like a banana around the edge of a suburban crescent.
There is a pond in its huge forecourt with turtles and ducks. Television screens in its ground-floor cafeteria relay live images of orangutans and chimps from the city's zoo. There is a grand piano in one corner, and above it a climbing wall rises to the main atrium's ceiling several floors overhead. For good measure, there is a sauna on the roof.
