Historical Notes
The history of the sanctuary begins in 1194, when Angelica Bonfantini donated the land for a church. The icon of the Madonna, of Byzantine origin (12th century), is said to have been brought by a hermit from Constantinople. In 1433, during a procession for rain, the miracle occurred: the deluge stopped at Porta Saragozza. Since then, every May, the Madonna descends into the city. The current building is Baroque, built between 1723 and 1757 by Carlo Francesco Dotti. Here are the key moments:

The world’s longest portico
The Portico of San Luca is an engineering and symbolic marvel. It starts at Porta Saragozza and winds for 3.8 km with 666 arches. The number is no coincidence: it represents the devil, and the serpentine shape of the path recalls evil defeated by the Madonna. The first arches are flat, then you ascend with 15 chapels of the Mysteries of the Rosary. Every 20 arches, a chapel. The Arco del Meloncello, designed by Dotti, marks the beginning of the climb. It’s a route I would take every day, if only for the shade of the porticos.

The Byzantine Icon and Art Treasures
Behind the high altar, a case protects the ancient icon of the Madonna and Child. Although tradition says it was painted by Saint Luke, scholars date it to the 12th century, Byzantine style. It is visible only at certain times (covered from 1:00 to 2:30 PM). The sanctuary also hosts masterpieces: Guido Reni’s Madonna of the Rosary, Guercino’s Christ Appearing to His Mother, and works by Donato Creti. The dome, 42 meters high, offers a 180-degree panoramic view of Bologna and the hills – not to be missed.

When to Go
The best time? A clear spring dawn. The portico is lit by the rising sun, and the city awakens below you. Alternatively, late afternoon: the warm light on the hills is magical. If you want to experience tradition, go in May during the procession of the Madonna: the icon comes down to the city and the atmosphere is festive. Avoid the midday hours in summer—the climb under the portico is cool, but the sun beats down hard on the square.

Nearby
Two ideas. Certosa di Bologna (a short walk from Porta Saragozza): a monumental cemetery, almost an open-air museum. Here rest Lucio Dalla and Giosue Carducci. Sentiero dei Bregoli: an ancient mule track starting from the church of San Martino and arriving near the sanctuary, for those who want a more rustic alternative to the portico. Both places enrich the visit with a different touch.

💡 Did You Know…?
According to tradition, the 666 arches of the portico symbolize the devil, defeated by the Virgin: the portico winds like a serpent but ends at the foot of the sanctuary. A miracle in 1433, when rain stopped as the icon passed through Porta Saragozza, gave rise to the annual procession that still takes place every May.
