The portico with its non-uniform supports reveals some unique details in its multiform design.
The capital of the corner pillar boasts highly skilled workmanship and reveals a round effigy of Giovanni Bentivoglio, who was head of the city during the last forty years of the 15th century. It was thought that it may have been a very rare artefact belonging to the destroyed Palazzo Bentivoglio (located in the current area of the Municipal Theatre), but recent studies cast serious doubt on this attribution. These two capitals made of Istrian stone and positioned not far from where Augustus the Emperor is depicted, refer to the golden Bentivoglio era that characterised the city of Bologna during the Renaissance.
The building, passed down from the Tuate family numerous owners throughout its existence, records the details of its passage from Gothic origins, through the Renaissance period and on to the splendour of the Baroque era.
