The Salt Square is a medieval marketplace built-in 1242 as a salt marketplace, adjacent to the old town's main square.

In the middle of the 15th century, a horrible action occurred here. A Franciscan preacher and priest, John of Capistrano, Who made a name for himself as a Jew-hunter, arrived in Wroclaw started preaching against the Jews. He accused the Jews of sacrilege and commanded his followers to burn forty-one men, expel all the others, and confiscate their properties. It would take two hundred years for the Jews to return to Wroclaw.

Only in 1996 did this tragedy receive physical reference by a flame-like monument erected by the artist Adam Wyspiański in the center of the square. Today the square serves as a flower market, active almost 24/7.
