Ein Wegfuhrer durch das Judische Kielce

Where does one start today to explore traces of the Jewish past in Kielce, discernible in the contemporary city only to the experienced eye of someone with at least some knowledge of Jewish culture and customs?
Of the 54 000 residents of pre-war Kielce, 18 000 were Jews. In other words, one-third of the town's population was Jewish.
The world of Kielce's Jews is gone. But the memory must not be lost.
