Holocaust survivor Yehudis Pshenitse has recounted the efforts of a parish priest from Nowy Dwór to save her life after the murder of more than 2000 Jews in Rembertówghetto in August 1942. Hiding her in his cellar, he gave her false papers identifying her as a Christian. Betrayed to the German occupying forces, the priest was tortured. He was released, but mortally wounded. Pshenitse described how he blessed her before dying: 'Once again, he asked [his housekeeper] that I be hidden in a safe place, and then he died'. The housekeeper took her to Modlin, where she was able to survive, living 'by her own wits, posing as a Christian child'.
The Israeli city of Holon has a Nowy Dwór Street (רחוב נובידבור). The name was given at the request of survivors of the Nowy Dwór Jewish community, who arrived in Holon after 1945.
