Nothing else in the world matches this covered walkway for sheer length: 3,796 meters and 666 arches climbing from the city gate at Porta Saragozza to the hilltop Sanctuary of the Madonna di San Luca, built between 1674 and 1739 specifically to shelter an annual procession carrying a Byzantine icon of the Madonna down into Bologna each spring.
Bolognesi walk it today for fitness, for penance, or simply for the view that opens up gradually as the arches climb the Colle della Guardia, and UNESCO recognized the whole system of Bologna's porticoes, this one included, as a World Heritage Site in 2021. Every May, the icon still makes the same descent it was built to protect.
