The region is rich in references to Jewish history, including Gora Kalwaria, long ago dubbed “the new Jerusalem”, the very large pre-war community of Lodz, and the capital Warsaw, where Jewish cultural life flourished until 1942 and even that year, when plays were performed in the spirit of the Resistance in the Warsaw ghetto, where Jews were walled up and starving, before being sent to Treblinka. Warsaw‘s Jewish memory is still alive and well today in a number of places, not least the Polin Museum.
