"Leonessa d'Italia" means "lioness of Italy" and is the nickname of Brescia, a city and "comune" in the Lombardy region of northern Italy.
Its name in Roman times was Brixia and Roman buildings can be seen in its
old town. Brescia has a picturesque piazza known as Piazza della Loggia (the first stone of the associated palazzo, Palazzo della Loggia, was laid in 1492, intended to symbolise good governance to the populace).
Now for the Charlemagne connection.
A former monastery called San Salvatore, where Desiderata (whose name in Latin means "things desired"), wife of Charlemagne (King of the Franks, later King of the Lombards, who gave his name to the Carolingian Empire), is reputed to have spent her exile, has now been turned into a museum,
San Salvatore became a
UNESCO World Heritage Site in 2011.
