In 1775 after a drought and following shortage of water in Piran a cistern was constructed on the Old Square (today´s 1st of May Square). At the right of stairs in the south there is an allegoric statue of Legality. In the shield there are the coats of arms of Piran and of families Bemba (right) and Marcello (left). At the left side of the statue there is a sitting hen of stone.
