Palazzo Pretorio
In front of the Consuls Palace there is the incomplete Gothic architecture of Palazzo Pretorio (1349), modified in 1475 and again in 1600, originally made up of three wide overlapped halls, each of whom covered with cross vaults resting on a unique central pillar; it was enlarged in 1800 and is now the municipal seat.
To the left the square is closed on the North-East side by the neoclassical Ranghiasci-Brancaleoni palace combining pre-existing buildings according to English models.
