pongoland

This dramatic roof belongs to "pongoland". And because it's the monkey house in the zoo, it does.
Actually it's full of different sorts of primates who live in relatively natural surroundings (no cages). Sometimes I wonder what they think about the masses who plaster their noses to the windows in their homes. They are intensively studied by the folks at the Max Planck Institute who often report new delevolpments in their understanding of the animals.
