Stolpersteins in Prague

Stolperstein is German for 'stumbling block'; the plural is Stolpersteine.  In the Jewish quarter of Prague there are many of these brass inserts in the cobbles bearing the name of a Jewish person or persons who died or who were persecuted at the hand of the Nazis at prisons, euthanasia facilities, sterilization clinics or concentration camps.  Others memorialized emigrated (assuming they were prepared to hand over all possessions and money to the Nazis before departing) or committed suicide.
