The Marian shrine is mentioned in the report of the 1573 pastoral visit, where the sanctuary was listed as having landed estates and bequests. In 1639, at the behest of Cardinal Cesare Monti, care of the shrine passed to the Carmelites of Concesa, who maintained it until the Napoleonic suppression of the religious order. It was sold to the Resta Pallavicini family, who permitted the construction of the portico in the late 19th century. In 1988, a ceramic painting by Tindaro Calia was placed on the pediment. Tradition holds that the Virgin appeared there to a peasant couple. A beautiful walnut portal, carved from a single centuries-old tree and finely carved with eight panels, leads into the small, intimate sanctuary. On the altar is a 16th-century fresco of the Virgin and Child, while on the walls are contemporary frescoes of Saints Catherine of Alexandria and Catherine of Siena, both well-crafted and recently restored. Today, the Sanctuary is still highly venerated, with pilgrims from all over the area coming to pray to the Madonna of Rezzano. Rezzano has always been the protective umbrella of all the surrounding towns. The Sanctuary is dedicated to the festival of the same name in the town of Truccazzano, held every year on the first Sunday after May 5th, the anniversary of the apparition of the Virgin in the locality of Vignazze di Truccazzano, where she ordered two shepherds to build a sanctuary in her everlasting memory.
