The arch is the starting point for the 3.8-kilometer portico walk, which consists of exactly 666 arches.
The number of arches in the portico leading up from the Meloncello is often interpreted symbolically as the serpent being crushed under the foot of the Madonna.
The structure was specifically built to allow pedestrian pilgrimage traffic to cross over the then-busy carriage road without interrupting flow.
The Meloncello ravine, which the arch spans, was historically a site of several smaller chapels before the current arch was commissioned.
Carlo Francesco Dotti, the architect, is the same designer responsible for the current form of the Sanctuary of the Madonna di San Luca at the top of the hill.
The arch serves as a bridge for a pedestrian path that splits into two levels to accommodate the steep gradient of the incline.
During the annual 'Madonna di San Luca' procession, the icon is carried through this arch as it descends from the hill into the city center.
The Arco del Meloncello is an 18th-century Rococo structure that functions as a monumental gateway over the busy Porrettana road in Bologna. Designed by Carlo Francesco Dotti and completed in 1732, it serves as the critical transition point where the world's longest portico begins its ascent to the Sanctuary of the Madonna di San Luca. The arch effectively connects the urban grid of Bologna to the steep, wooded foothills of the Colle della Guardia. Its architecture features a characteristic complex layout with staircases and passages designed to manage the elevation gain for pilgrims. The structure sits at the junction of the flat city plain and the start of the steep walkway leading to the hilltop basilica. It remains an essential node in the UNESCO-recognized porticoes of Bologna system.
From the pedestrian walkway looking upward toward the rising porticoes of San Luca.
Begin your ascent to San Luca from here early in the morning to beat the heat during summer months.
Bring a water bottle as there are few filling stations between this point and the top of the hill.
Wear shoes with good grip, as the portico path can be uneven and steep.
Do not attempt to climb the exterior of the arch structure itself; stick to the designated walkways.
Respect that the portico is a protected cultural monument and a regular path for local joggers and pilgrims.
