Erected in the 18th century, its northern side was built on top of a large section of the Etruscan walls, the only section the inside of which is visible, which is a continuation of the other section beneath the present Piazza Ermini and Via del Verzaro, and further on from the section in Via Cesare Battisti. The mansion was purchased in 1840 by the Marchesa Marianna Florenzi (1802-70), who subsequently married a Mr. Waddington, and who held a renowned literary salon here. Further on, at number 7 of Via dell’Aquilone, near the Department of Classical Studies of the Faculty of Letters, there is a gallery of plaster casts featuring casts of Etruscan, Greek and Roman statues.
