The square was founded in 1903, and until 1940 it was called the Square of Rieger, after Czech politician and patriot František Ladislav Rieger (1818-1903). During German occupation it was named the Square of Methodius. Native of Greek Thessaloniki, Methodius (815-885) together with his younger brother Cyril played important roles in rise of our literature and development of Christian culture in the Great Moravia. After end of World War II the name of Rieger was returned to the square. In 1948 it was named the Square of Syneks Brothers. Otto Synek (1900-1941) was a member of parliament and a journalist, Viktor Synek (1903-1941) a journalist. Both of them paid for their resistance activities against the German occupants with the highest penalty; they were executed in 1941.

Nowadays, the square is surrounded mainly with perfect apartment houses. There is a line of electric railway running through the centre, which has also the stations there. These stations are being used by one line of public traffic bus.

In the thirties the Civil savings bank in Vršovice had its branch there. Now there is one of the branches of Česká spořitelna.
