Antwerp ZOO is also a very special place because it has a programme to help save animals that are endangered such as bonobos and okapi. What are they? You may ask – well come and visit the zoo to see who's who! The Zoo's beautiful buildings and garden have been listed as monuments and when it was built in 1843, more than 150 years ago it was just outside of the city's walls. Now – the city has grown so much that the ZOO is now in the middle of town and is a green oasis next to Central Station.
