According to an archaeological reconstruction, the house at number 1 in this square may have been the seat of the medieval municipality of Santa Fiora. At that time, in addition to the portal which is still in use, the building had an entrance on the first floor on the right side served by an external staircase. A small noble palace was later built on the opposite side. According to oral tradition, between the 19th and 20th centuries, the stonemasons who had workshops in the town sculpted the beautiful neo-Gothic fountain in the centre of the square.
