My guidebook mentioned this land museum in Braunschweig is much better than its equivalent in Hanover and though I have never been to the latter, this one was really great and I reccomend it. And much bigger than I thought - you really need a couple of hours at least.
I found the inflationary notes really interesting - one was for 200 billon Deutschmarks!! The depiction of Braunschweig before and after the 'bombennacht' on 15th October 1944 were interesting although horrifying.The admission price is an affordable 2.50 Euro and it is open every day except for Monday with extended hours on Thursday evenings.
