The original palace was commissioned in the late 16th century by Count Becchi.
The palace is notable for a fine decorated frieze below the roofline and a marble telamon-like figure at the corner of the building, depicting the god Janus, sculpted in 1576 by Prospero Sogari .
By the early nineteenth century, ownership of the palace passed to the aristocratic Chioffi family, who refurbished the facade to its present Neoclassical style.
Luigi Magnani endowed the Magnani-Rocca Foundation to display his art collections at his villa at Mamiano di Traversetolo.
This palace, restored by Ivan Sacchetti, was purchased in 1984 by the town from the estate of Luigi Magnani, and is now used for special exhibits.
