Almost every big room of Palazzo Pubblico frescoes, quite uncharacteristic for the period, because they were written at the behest of the rulers of the city, not at the behest of the church or religious brotherhood .  Another unusual feature of these murals is that many of them depict secular subjects, rather than religious, that was typical of the Italian art of the 14th century .  The most famous frescoes of the Palazzo are those that are located in the Hall of the Nine - they are painted by Ambrogio Lorenzetti, and collectively known as "Allegory and Effects of the good and bad of the Board" .  In the scene with the image of good governance can be seen thriving city with people dancing in the streets, while misrule rampant crime and roam the ruined city sick people .  Unfortunately, this cycle, as well as many other frescoes of the Palazzo, severely damaged .  One reason for this is that once the building housed the store salt, which has absorbed all of the moisture from the walls, thus causing drying plaster and peeling frescoes .
