The Berlin Wall outside exhibit close to Nordbahnhof is a great place for both children and adults to learn more about the Berlin Wall. There is a vast open space which used to be the Death Strip with a wall of poles to represent the line of the Wall. There are audio posts with both English and German audio the time of the Wall and many parts of the original infrastructure of the Wall for example lights.
It is safe area for children to run about in.
Further down the road as part of the visitors' centre, there is an observation tower which overlooks a preserved section of the Wall and Death Strip with a guard tower (see photo above). There are stairs and a lift but you need to ask at the information desk on the ground floor to use it. It also offers great views across the city.
Opposite the open area of the exhibition is a small visitors' centre with an excellent gift shop, displays and toilets with changing facilities for babies. Entry is free for all the exhibition; inside and outdoors.
The website below has a lot more detail about what is available at the site. We barely scratched the surface in one morning.
Address: Bernauer Strasse 119, 13355 Berlin
