I don’t usually recommend that tourists visit Warsaw for their first trip to Poland. There are plenty of interesting things to see there, but an international tourist is going to have a certain expectation of what they will want to see, which is mostly Kraków’s medieval center and the Jewish history. That is course is a very narrow slice of Poland, which is a rapidly developing modern European powerhouse in its own right.
Another interesting thing is that almost all “old” things are materially mostly new, like the Ship of Theseus. Most structures take regular refurbishment to stay standing. So in a way, while Warsaw Old Town is materially new, the form is old, so it is still in some sense old. This is in contrast to Gdańsk’s old town which are facades slapped on top of communist block buildings meant to create a Polish themed city out of the former German city, much more Disney than architectural conservation.
