The main entrance, placed in front of the Cathedral of San Giorgio called the Volto del Cavallo, is flanked by the equestrian statue of the marquis Niccolò III and that of the duke Borso d'Este seated on the faldistorio holding a sceptre in the act of administering justice.

Inaugurated on 19 December 1454, it was first placed in front of the Podestà's residence (to the right of the then Palazzo della Ragione) and a year after Borso's death, in 1472 it was moved next to his father's, where it remained until its destruction in October 1796 to obtain bronze for cannons.

Between 1924—1928, the façade in front of St George’s Cathedral was rebuilt in neo-medieval style, while the remaining part along today’s Corso Martiri della Libertà had already been remodelled in 1738.

The city administration, represented by the podestà Renzo Ravenna, in turn supported by Italo Balbo, played a large part in this reconstruction.

In the infradoxes of the Volto del Cavallo, he executed the ornaments depicting the Este coats of arms (referable to Niccolò and Borso) and phytomorphic elements: red flowers divided into groups of three in which one towered above the others, reminiscent of those present in the upper loggia of Casa Romei (attributed to Desiderato da Lendinara), to which Medini probably drew direct inspiration.
