I visited this museum on a sunny Saturday afternoon in October by myself. Even though there's a LOT of plaque/caption reading available, it's clearly a newer museum insofar as it seems to embrace a variety of multimedia for conveying information regarding the heroic uprising and the utter destruction of Warsaw. It's a tale of bravery and sacrifice but also a tragic disaster of human misery and cruelty, and the museum clearly conveys this with content, lighting, sounds, etc.
However, my visit was much less than I had hoped, especially relative to the POLIN Museum of the History of Polish Jews, which is an excellent museum. First, the Uprising Museum is laid out in a completely confusing manner. There's no central story line -- I mean, there *is*, but this museum doesn't tell it or lay it out in any coherent way physically. I was a third of the way through the ground floor before I realized I *should* have gotten an audio guide as my confusion as to what I was seeing and how it fit together grew -- without one (and an accompanying map), you are very likely to get lost within the content immediately after entry, as it starts off in 1939, then darts forward, then backward, then sideways, and back again.
But even WITH a map and an audio guide (which I went back to get), you'll see the 'exhibition route' crosses back upon itself numerous times -- it's a like a maze! The mezzanine level in particular is well hidden -- I'm pretty good with maps and yet it took me a good 10 minutes to figure out that it wasn't where I thought it was. There are no signs indicating what room/number you're in at any given moment, so you have to triangulate between the map, the audio guide, and the general shape/orientation of whatever room you're in to figure out where you are and what would be helpful to listen to on the guide. It's fair to say I got 'lost' content-wise on every floor at least once...and I got increasingly frustrated as I continued thru the museum.
Second, the museum was *very* crowded. Although I had to book a timed entry, I showed up 20 minutes early and got in without any issue. I thought the timed entry bit was to reduce crowding during COVID times, but evidently it doesn't really matter. And even though there are signs indicating that masks are to be worn (and how to wear them properly), there are some people that just don't get it...or don't *want* to get it. So, if you're COVID-nervous, this isn't the place for you.
In summary, there ARE some elements in the museum that are extremely well done -- e.g., the movie toward the 'end' featuring a flyover of Warsaw in summer 1945, and the 'Reflections' exhibit -- but the whole is less than the sum of the parts in this case. It was a frustrating disappointment.
