Siedlce was one of such dark places. Here is the photo that is archived in Yad Vashem Museum that show one of the places ... seems to be a case where the gravestone is almost intact. It is not clear if this photo was done during the war when the payment was done or was it after the war if and when the stones were collected and placed elsewhere. Here we can see that the photo was taken on the street an not in the cemetery.
