Before World War II more than 20 percent of world's Jewish population lived
in Poland. They settled mainly in the eastern parts of the country, like
the north-eastern city of Bialystok, where in 1937 they made up almost
half of the population. But in the Bialystok region today, once home
to 300,000 Jews, only a handful are left. Which prompts some to ask - what
would Bialystok and other Polish communities - look like today - if it
weren't for the holocaust? An exhibition in Warsaw is trying to answer
that.
