 The statue of Pope Paul V has stood in the centre of the square next to the fountain since 1614.In the 16th century, the 'grand square' (now the Piazza Tre Martiri in honor of three civilians hanged by the retreating Nazis at the end of World War II), which was where markets and tournaments were held, underwent various changes.A small temple dedicated to Saint Anthony of Padua and a clock tower were built there, giving the square its present shape and size.
