Various hypotheses have been advanced as to the meaning of the town's name. One explanation for the word "Rovello" is its derivation from the
Celtic words
rose (valley) and
vel (fort); i.e., "valley fortress". If that interpretation is correct, it would point to a very early settlement, since groups of
Celts settled in parts of northern Italy up to about 300 BCE. The area was definitely inhabited in Roman times, as confirmed by the 1977-78 discovery of some 40 tombs between Via Manzoni and Via Carducci. The tombs contained everyday objects related to daily life (mirrors, bracelets, lamps and vases, etc., as well as coins dating from the 1st century BCE up to the 1st century CE. 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. In the countryside near
Saronno was the residence of
Matteo II Visconti (c. 1319–1355). In 1519 the local council of heads of families decided to entrust two local churches to the
Carmelites, who occupied the Rovello convent till 1653, having pledged to celebrate a daily Mass and to teach reading and writing to local children. Early in the 17th century the monks began observing a feast day on the third Sunday in July with an annual procession and carrying a statue of the Madonna. In October 1652 Pope
Innocent X decided to suppress all smaller monasteries, and Archbishop
Alfonso Litta closed the Rovello monastery in 1653, ceding its building and property to the parish. In 1677, however, Marquis Cesare Pagani, a leading figure in Milan's public life, received permission to erect a chapel dedicated to Santa Maria del Carmine. He donated a wooden statue of the Madonna which is still revered today. ==Later history==
