The Trion Summaxon (Three Allies) square or "Diadoxou" (Crown Prince's), as it was called at that time. It stands at the beginning (near the Port) of Agiou Nikolaou street and leads to the Mole and the Lighthouse, once, of Patras. Today a giant floral clock decorates the square. In the place of the red-tent building today stands the National Bank of Greece.
