The ghetto wall
The memory of the Warsaw Ghetto is very much alive in Warsaw, and it is something we should remember. Hopefully to prevent a repeat of it in the future. While there is only 1 small piece of the ghetto wall still standing, there are plenty of reminders of the ghetto. In particular you keep coming across these brass plaques commemorating where the walls used to stand. A sad reminder of our history, and hoping it will not happen again.
