I was able to drive through Celle the Sunday before last, and I have to say, as wonderful as the photos are, they pale in comparison to the display. It's huge! Almost everyone at the exhibit was staring at it in stunned silence. It's beautifully arranged and covered with wonderful and very lifelike vignettes that add a "human aspect" to the innumerable ranks of soldiers.
In an anteroom there's also a beautiful diorama of the Hanoverian Army's celebrations on the erection of the Waterloo "victory column", made with "flats" from a long-extinct company. And the rest of the exhibit is very interesting as well - lots of worthwhile information about the KGL and other German troops at the battle.
