The palace, built at the end of the fourteenth century, is the ducal residence of the Caldora family, then feudal lords of Bitonto. Among the first noble residences of the city, on the entrance to the sixth acute stands out the civic coat of arms, with an olive tree in the center. Various restorations have left its austere appearance unaltered.
