Sienna Street, one of the borders of the ghetto, is separated by walls only from alleys; houses with courtyards overlooking Złota Street, the so-called “other side”, are – for the time being – separated from the outside world by barbed wire. Most of the smuggling takes place here. Our windows overlook such a yard. It is busy all night, but when the morning comes, vegetable carts line the streets and shops shelves are laden with bread.

The flat of Mary Berg, the author of the above words, was located near the fragment of the ghetto wall that has survived to this day. What happened to the Weinbergs during World War II?
