The palace dates from the late fifteenth century when the rooms were built next to the tower and onto the loggia. The portico of the palace was the meeting place for popular assemblies, the market and the social centre of the town. The building was then remodelled over the centuries.
Inside the palace there is a courtyard where is depicted San Cataldo, then protector of the town. At the beginning of the eighteenth century the building threatened to collapse and began to build the first of four spurs that currently can be seen in front of the portico. In the mid-nineteenth century the top floor was added with the clock and the large balcony.
The facade makes great use of local lava stone, very dark and grainy. On the right side of the building one can recognise the ancient tower.
