Placed at the center of the street "la piaggia", was built by the tyrant of Corinaldo Antonello Accattabriga, in the second half of 400 to supply the well of polenta to the neighboring houses, was later buried with the restructuring of the staircase in the early years of 900. It was rebuilt in 1980 to set the scene of the Contesa del Polenta well that every year commemorates the fall of the sack of flour in the well. It is an old rumor that the people of Corinth used to make "polenta in the well", the truth is that in times long gone, a man climbed the beautiful, long, staircase of the town (Via Piaggia) with a sack of corn flour on his shoulders. When he reached the well, exhausted, he put the sack on the edge to catch his breath. Out of bad luck, the sack fell inside the well. The poor man in an attempt to retrieve it fell into the well, this did not go unnoticed by the gossips of the country, who did not see him resurface, began to say that he was eating polenta in the well, some swore they had seen throw even pork sausages in the well. The rumor that wanted to pass the people of Corinth as "picchiatelli" and "polentari", soon crossed the borders of the entire region. From "picchiatelli" to genial the step is short.
The story soon became the starting point for the annual historical commemoration in costume of the sixteenth century "La Contesa del pozzo della Polenta" that now in its thirtieth edition, takes place on the third Sunday in July and is the oldest historical commemoration in the province of Ancona.
