Palazzo Aventi stands between Alberto Lollio Street and Armari Street. It was born as “Palazzo della Rosa,” so named because of its proximity to the church of Santa Maria della Rosa, now demolished. The palace was bought by Duke Alfonso I d’Este in 1525 and then restored to give to Laura Dianti, his companion after the death of his second wife Lucrezia Borgia.
For some years, the palace became a veritable “court” and intellectual circle of Dianti, hosting artists, writers, poets and personalities of the time.
In the 19th century, part of the building was used as the headquarters of the Circolo dell’Unione, the “first-born of Italian circles,” according to the Encyclopedia Treccani. The Circolo, which has always gathered distinguished members of the city, is known for the patriotism of its early members, who continue to this day to be involved in social work.
