It is a huge museum located in the middle of the Tervuren park that will show you a lot of the African culture, but mostly in a traditional way. It covers a range of topics, going from animals, insects, civilisations and many more!
If you're interested in history and getting to know the African continent, then you should definitely go and have a look! The entrance is quite cheap and it will take you approximately 1 or 2 hours to visit it.
