The square, once called Piazza Grande, takes its name from the two equestrian statues in bronze which stand near to the City Hall. In this square there are several buildings belonging to different eras including the imposing Palazzo Gotico and the Governor's Palace: two fascinating scenic backdrops that counterpoint the exuberant masses of the two bronze statues made between 1620 and 1625 by the Tuscan sculptor Francesco Mochi (1580-1654). The two equestrian monuments depicting with the styles of Baroque the Duke Ranuccio Farnese and his father Alexander, was commissioned by the same Ranuccio in 1612 but only in 1620 the sculptor Mochi, after some studies on similar subjects already covered by Donatello in Padua and Verrocchio in Venice, gave body to the statue of Ranuccio, representing it in Roman costume and with a scepter in his hand. Five years later concluded the statue dedicated to Alexander, characterized by a fiercely energetic enthusiasm that fills the mantle of Duke. Even the reliefs on the sides of the bases of the two sculptures were done by the same artist (1625-19), who are donating to the monument of Ranuccio an allegorical representation of Peace and Good Government, and to the monument of Alexnder a representation of the assault of the city of Antwerp (1584), Alexander received the ambassadors of Queen Elizabeth (1587) in memory of the qualities of Duke, governor general of Philip II of Flanders.
