The Arena lets you experience the fascination of mobility in the open air. Amongst other things, it features a large boating pool. During the summer months, you can take a pedalo out between the palm trees and sun loungers and try out little battery-powered boats. Scooters and play buses are provided for crossing the large Arena. The museum's garden has go karts on which 3 to 12-year-olds can learn the rules of the road. The roadworks arena is where the children can use excavators and bulldozers to load and transport various construction materials, mend roads and lay paths.
