Interior view
The fa�ade and the internal courtyard of the Palazzo Ranuzzi (now the Palazzo di Giustizia) were probably built on a project by Andrea Palladio. The spectacular staircase was created by Giuseppe Antonio Torri (1655-c. 1713) and Giovanni Battista Piacentini at the end of the seventeenth century.
