Pawiak

Pawiak was a political prison in Warsaw that was used by authoritarian leaders up to 1944, when it was destroyed by the retreating Nazis.

37,000 (of the 100,000 people that the Nazis incarcerated there) died, either there or at concentration camps. There are tablets like this dotted round the outside of the building. I think they comemorate what went on in there. I have no idea what the tablet says, however.
