@elefante That's the old Africa Pavilion building. It's closed now because apparently the building was too old and became unsafe. It used to be my favorite part of the zoo when I went as a kid. I remember it had a tall, round colobus monkey exhibit right in the middle of the building. It also had meerkats, dik-diks, a fennec fox, mandrills, dwarf crocodiles and others I'm sure I'm forgetting. I just remember it being full of smaller African animals and birds. And it was very lush and full of plants. It really felt like you were walking through a jungle. Always smelled very strongly of poo, though.
