Piazza San Michele takes its name from the former Church of Saint Michael in Castello, which was the seat of the Confraternity of the Disciplined from the 15th to the late 18th century. The statue that decorates the building depicts Michael archangel victorious over the devil, with his sword and the weighing scales with which he weighs the souls of the dead. An epigraph recounts the tale of Luigi Bani, one of the founders of the Santa Fiora Workers' Society (1889) and director of the Rosselli company at the Siele mines, who was robbed and killed while on his way to deliver wages to the miners.
