The 666 arches of the portico are said by some to symbolize the victory of the Virgin Mary over the serpent, represented by the devil.
The sanctuary houses a Byzantine icon of the Madonna and Child, which, according to tradition, was brought from Constantinople to Bologna by a hermit in the 12th century.
The portico was built in stages between 1674 and 1721, funded by donations from both nobility and common citizens.
The sanctuary's position on the Colle della Guardia has been a site of religious devotion since the building of a small church in 1194.
The annual procession of the icon to the city center has occurred every year since 1433.
The Santuario Madonna di San Luca is an 18th-century basilica situated atop the Colle della Guardia in Bologna. It is famously connected to the city center by a 3.8-kilometer-long portico, the longest in the world, consisting of 666 arches. The current church was built between 1723 and 1757, replacing a 12th-century chapel dedicated to the Virgin Mary. The sanctuary serves as the final destination for an annual religious procession that carries a Byzantine icon of the Madonna and Child from the city’s cathedral to the hilltop. Architecturally, the building is defined by its elliptical floor plan and twin bell towers. It sits at an elevation of approximately 280 meters above sea level, providing panoramic views of the Po Valley and the Reno valley. The site is a major pilgrimage destination and a UNESCO World Heritage site as part of the Porticos of Bologna series.
