 During the Middle Ages the chaplain of the Rovello parish was Goffredo da Bussero, sometimes known as Gotifredo, a priest from Milan credited as the author of "Notitiæ Mediolani Sanctorum", completed in the late 13th century, an important source for the diocesan history of the area.From this work it appears that four chapels were originally dedicated to St. Andrew (not mentioned in later centuries); Saints Euphemia and Ursula (recorded until the 15th century); Santa Maria della Lura; and St. Peter, since the 12th century dedicated to St. Paul as well.Little or nothing is known of Rovello during the rest of the Middle Ages, except for a short-lived peace treaty signed in Rovello and Lomazzo between the Guelphs and Ghibellines, warring factions from Como and Milan.
