The large walk-through enclosure for barbary macaque in Givskud Zoo. A quite interesting thing that I've read in a book about the zoo is that the monkes don't have a house but had one before. When the enclosure was built they built a house for the monkeys but they refused to use it. Even during powerful snowstorms in the middle of the winter the monkeys refused to go inside. Instead they sat outside. After a couple of years they removed the house and instead built small shelters in the enclosure. The monkeys are outside all year round
