The Territorial Informative System of the Municipality of Bologna has developed a map of the 62 kilometres of porticoes that wind around the whole city. The result is a truly arresting display of collective heritage present everywhere, both in the centre and in the suburbs. As much as 42 kilometres of portico structures are located in the ancient heart of Bologna, while 20 are spread throughout the city outside the ring road.
The survey was made possible also thanks to the reports of citizens who responded to the appeal issued by the Municipality through its social profiles (Facebook, Instagram, Twitter). Many sent photographs and described the features of less known peripheral porticoes, which show that this ancient architectural feature has never been abandoned, but, rather it, has survived the evolutions and transformations of history. Moreover, the 20 kilometres surveyed outside the historic centre are the result of a very rigorous selection, since they only include the porticoes in public use, with the presence of commercial premises nearby, and exclude all the ones whose sole function is access to buildings.
