Of particular historical interest are the spaces that connect the Palazzo to the so-called Masseria located on the east side of Piazza Broletto. They correspond to the part above the vault, sometimes incorrectly referred to as Arengario, which today divides the same square from Via Ardigò. The interest is due not so much to the artistic evidence as to the fact that over time these places were used for many different purposes, even as a prison in the nineteenth and twentieth centuries.
