This building has extremely ancient roots and its floorplan is influenced by illustrious pre-existing constructions, i.e. the Imperial Fortress that was destroyed by the local population in 1115. At the start of the 14th century, the banker Alberto Conoscenti commissioned a significantly sized palazzo. The portico, influenced by the transformations taken place over time, presents a variety of shapes and different types of decorations.
A fragment of the walls in selenite dating back to the 5th-6th century AD can be seen in the courtyard, testifying to the antiquity of the location.
