Open Gallery

The central element of the building is the beautiful gallery. It has arches supported by two columns and a shaft decorated in a relief of foliage motifs, attributed to Jacopo Barozzi (Vignola).

The upper part of the gallery, on the main floor, was closed during the 1700s. This was a time when the palace passed to the Pallavicini family, when numerous interventions led to modernizations but also the loss of works such as the frieze with the stories of Gregory XIII, as was recorded by chroniclers of the time.
