A living map of Europe “occupies” the lobby floor: the morphing boundries of the German empire over centuries is projected onto a map of Europe. The display is a brilliant means of simply conveying the evolving history of power.
The museum is layed-out logically. Walk through the second floor, which will deliver you from 1 BC to 1918, then descend to the first floor to take-in 1918 to the present. You’ll learn a lot, and some of the images (none exactly cheerful) will stick with you for awhile.
