Bologna: I Portici
The porticoes of Bologna (UNESCO 2021) form the most extensive and continuously inhabited covered pedestrian system in medieval Europe — 62 km of arched walkways that have lined the streets since the 11th century CE, sheltering the oldest university community in the world (founded 1088 CE) from rain and sun, with the 12-km pilgrimage portico to San Luca as the longest covered walkway on earth.
At a glance
Bologna portici (the most precisely Bologna zone Bologna Emilia-Romagna Italy 44.4949 N 11.3426 E UNESCO WHS 2021 reference 1673: the specific history of the portici system (the oldest surviving porticoes: the porticoes of the Palazzo della Mercanzia (1384 CE) are the oldest porticoes in Bologna that survive substantially intact today; however, the portici system is documented much earlier: (a) the 1041 CE city statute (Bologna was one of the first Italian communes to achieve self-governance (the city statutes of 1041 CE are among the earliest in Italy)); the 1041 statute required new buildings on streets in the city center to include a porticus (a ground-floor covered walkway) at the builder’s expense; (b) the 1288 CE statute (extended the porticus requirement to all streets within the city walls and specified minimum dimensions); the specific reason for the portico obligation: the University of Bologna (founded 1088 CE; the oldest university in the Western world; from its founding, the students lived in rented rooms across the city and needed to walk to lectures in all weather; the university’s location changed frequently in the first 2 centuries CE as masters moved between rented lecture rooms; the portico provided shelter for the student population moving between lodgings and lectures)); the 62 km statistics (the 62 km total is the count of all covered walkways in the current municipality of Bologna; the 45 km continuous covered walkway in the city center is the largest contiguous covered pedestrian network in the world; the 12 km San Luca portico is the longest single covered walkway in the world).
Key facts
- The 666 arches of the San Luca portico and why the number has a specific religious meaning that is not accidental: the San Luca portico (the full route: the Sanctuary of the Madonna di San Luca (on the Colle della Guardia; 291 m elevation) is connected to the Arco del Meloncello (a triumphal arch designed by Carlo Francesco Dotti (1670–1759 CE) in 1732 CE, 50 m from the Porta Saragozza) by a 3.796 km portico with 666 arches; the 666 number: the number of arches (666) was set deliberately by the architects and patrons of the portico (begun 1674 CE; completed 1793 CE: 119 years of construction; the arches were built section by section as funds were raised by the local nobility and guilds); the specific devotional mathematics: 666 arches × the prayer of 1 Ave Maria per arch = 666 Ave Maria recitations for the full pilgrimage walk; 666 Ave Maria = 6 Rosaries of 111 beads each = 6 Marian devotional cycles; the number is NOT a reference to the “Number of the Beast” (Revelation 13:18) — this is a recurring misunderstanding; the 666 is the product of the devotional calculation); the annual Ascension Day procession (the specific ritual: each year on Ascension Day (the Thursday 40 days after Easter) the painting of the Madonna di San Luca (a 12th-century CE Byzantine icon attributed by tradition to Saint Luke the Evangelist) is carried in procession from the Sanctuary down the 3.796 km portico to the Cathedral of Bologna (San Pietro), where it remains for a week before being carried back; the procession has been continuous since 1433 CE)

History
From the oldest university to the portico statutes to the construction of the San Luca portico to the UNESCO inscription (the most precisely Bologna portici zone history: the university origin (Irnerius (c.1050–c.1130 CE): the first documented lecturer at the Bologna law school; his glosses on Justinian’s Corpus Iuris Civilis (the Byzantine legal codification of 529–534 CE) were the curriculum of the school; the specific claim to 1088 CE: the date is established by a charter of 1155 CE in which Emperor Frederick Barbarossa granted protections to the students and masters of Bologna — the Authentica Habita of 1155 CE is the oldest surviving document recognizing a university community); the portico statutes (1041 CE: the first recorded portico requirement; 1288 CE: the comprehensive statute; the specific mechanism: the portico was built by the property owner but open to the public at all hours (unlike a covered market or arcade, which could be closed); the Bolognese innovation was making the ground-floor commercial space private but the walkway in front of it permanently public)); the construction of the San Luca portico (1674–1793 CE: 119 years; the project was proposed in 1655 CE by the Bolognese senator Angelo Ranuzzi; financed section-by-section by the city nobility and guilds; the specific construction sequence: each section (bay) of arches was built by a different noble family or guild, which carved its family insignia into the keystone of its arches; 334 different keystones carry 334 different noble family insignia); 2021 CE UNESCO inscription reference 1673.
