There are a large number of florists every day in this large square, which was chosen by the bourgeois class of the nineteenth century as their favorite place to walk. In the old days, on Sundays the tradition of selling flowers on the last day of the week arose in 1772, and the town has maintained this tradition Since then, Sundays are still the liveliest days here, with the market expanding greatly, and Sundays the days when locals come to sample the oysters on display outside the picturesque blue stall, on the edge of the wide plaza.
