We have been to Senkenberg Natural Meusem in Frankfurt, Germany and were impressed by its collections. My son was especially impressed by its dinosaur collection.
Senkenberg Natural Meseum, Frankfurt
Several days ago, I chatted with a friend who lives in Beijing and was told that there is one museum in Beijing which has also a great collection of dinosaurs. This museum is quite big and features many exhibitions where children learn not only through visiting but also through interactivity such as touching, assembling, games and so on. It looks like a great museum to be explored. I definitely put it into my list of places to visit in Beijing!
