De Ferraris–Regna Palace stands in the heart of Bitonto’s old town. The building unfolds around an irregularly shaped inner courtyard, revealing the layers of architectural history that have developed over the centuries.

The palace was initially built by the De Ferraris family, of Genoese origin, who settled in Bitonto in the 14th century and rose to prominence under the favor of the Angevins. The family’s coat of arms—featuring a cross with two lilies above and two roses below—can still be seen on Pinto Arch and in the crypt of the Cathedral.

In 1575, the property passed to the Regna family, originally from Lombardy. The current building, Regna Palace, results from continuous architectural evolution. It transformed the original 14th-century structure through Renaissance additions between the 14th and 16th centuries, with further modifications continuing into modern times.

The main entrance, facing Cavour Square, features a monumental portal—a classical-style triumphal arch—marked by a bold and imposing entablature. Above the arch are two medallions with the profiles of Julius Caesar and Augustus—or perhaps the patrons themselves. A dedicatory inscription from 1586 states that the structure was built for private use and for the enjoyment of friends.

To the side of the portal, a delicate balustrade with slender columns runs along the courtyard wall, where a dramatic curved stone staircase rises with grace. Here, you can still spot the original window openings later converted into balconies. The palace’s façade on Cavour Square is further distinguished by an expansive stone balcony added after the original construction of the entrance portal.

The Regna family coat of arms is prominently displayed on the arch keystone and once again on the inner balcony, offering a visual signature of the family’s long-standing presence in this historic residence.
