The square is located on the southern side of the Duomo, which forms the Ghirlandina bell tower, a huge complex that has been declared a World Heritage Site. Located on the east side of the square, the Palazzo Comunale is a 17th-century building with a hallway that unites the old medieval buildings of the municipality and mind. The palace, which was in the Middle Ages several towers, one of which is called the tower cut because of the earthquake that was cut off, is today an L-shaped corridor. On the western side of the square is the back of the episcopal, while on the south side there is a modern building of a bank , As well as a gallery. This palace, designed by architect Giu Ponte, replaced a former building that was built in the style of the Romanian ministries at the end of the 19th century. The building was sold by the municipality to the local Cassa di Risparmio, and the building was demolished and replaced by the Gio Ponti building, which dealt with the problem by trying to modernize the grounds of the Municipal and Metropolitan Hall.
In the northeastern corner of Piazza Grande, near the Comunali Palace, there is Breda Ringadura, which is a large rectangle of more than 3 meters, probably originally from a Roman building. During the Middle Ages, Breda was used as a stage for speakers, but also as a place to carry out executions, to expose corpses (so that someone could recognize them) and to use them as a stone of shame. As the historical municipal archive shows, every debtor was insolvent on Market Day after wandering the field With a razor head and a special hat, preceded by a trumpet sound, and he had to announce himself until he had to "give his prey a rengadora, a well greased turpentine, three times saying three times Sido Bonis, Sido Bonis, Sido Bonis", which promises to repay debts with their assets It must occur for three consecutive Saturdays at the request of the d In which could well consider the possibility to recover his money, referring to the assets of the debtor.
