POLIN Museum of the History of Polish Jews is a museum on the site of the former Warsaw Ghetto. The Hebrew word Polin in the museum's English name means either "Poland" or "rest here" and relates to a legend about the arrival of the first Jews to Poland. Construction of the museum in designated land in Muranów, Warsaw's prewar Jewish quarter, began in 2009, following an international architectural competition won by Finnish architects Rainer Mahlamäki and Ilmari Lahdelma.
