The first door encountered on the right leads into a room in which no traces of decoration are visible. This room probably served the function of an antechamber to the apartment reserved for the lady.

Today, on the walls are two canvases, formerly housed in the Hall of Rings, depicting the portrait of Francesco Boncompagni, archbishop of Naples, and that of Ugo Boncompagni, father of Giacomo marquis of Vignola from 1577, future pontiff Gregory XIII. A small door leads to the room known as the Anticappella, which in the very early fifteenth century formed, together with the Contrari Chapel, the maneuvering chamber inside which were two winches with their servants who moved the portcullises, barring the passage to the inner courtyard when necessary.

In the triangular niche above the entrance door to the Chapel was recently placed the 15th-century style scagliola tondo depicting a Madonna and Child in the variant known as the Madonna of Humility.
