I haven't been to Prague, but I lived in Nuremberg for 3 years and commuted to 4 different locations weekly for my job. It's all that's been mentioned and more.
You have a lot of time to research and that's a good thing. Googling will help you to learn about the city and its history.
Here's a link to get you started. And here's another one.
I lived there from 1982 to 1985 in an apartment building that amazingly escaped the bombing. I took my husband there in 2009 and showed him my apartment building.
There was a young couple outside washing off their bikes. The man came over and asked why we were staring at the building and taking pictures. I told him about living on the top floor and working for the US Army.
He was only vaguely aware of the US presence there then and had no idea that Americans lived in the city and not on post at the time. Shoot, he probably wasn't even born back then.
Before the Rally Grounds were turned over to the German government, it was used as playing fields for the Army. We were invited to explore the interior structure. I was the only person who went. It was fascinating. The place was trashed and a mess. Except for an occasional klieg light and safe too heavy to move, there wasn't much there but rubble.
However, there was graffiti on the walls done by mostly US soldiers. I loved seeing their names, where they were from and the date they were there. I hope that historical record is still there and that the interior I saw can still be seen, but maybe made a little safer for visitors.
If you go, eat some Nuremberger bratwurst and Schäufele mit Knödel for me.
