If you are visiting Potsdam, this will probably be your first stop, and rightfully so. Apparently…read moreduring WWII it was heavily damaged and is now in an almost restored state. Still some work to do. You can climb the tower for a small fee (I was lazy and did not) and there is a suggested 2 euro donation as you leave. Perfectly legit and I was happy to oblige. The church itself is beautiful, but not overwhelming like some. Helpfully, there is an explanatory laminated page on the left, just as you enter, with a full history - available in 10 languages or so.
