The Panorama Museum in Bad Frankenhausen contains one enormous painting in the round by Werner Tübke commemorating the Peasants' War of 1524-26. Though commissioned by the government of East Germany, it is not in the Socialist Realism style, but references the masters of the German Renaissance. And because it's so huge there's room for Sebastian Brant's Ship of Fools.
I found out about this place at J. P. Kleiner's fascinating blog, The GDR Objectified, and the image comes from here. See also. And.
