Bologna is famous for its porticoes, which are a world record for overall extension throughout the city and for the length of a single work, with the 3796 metres of uninterrupted coverage of the San Luca portico.
The use of the portico in Bologna has ancient origins: it protects from sun and rain and creates an extension of the dwelling.
They even became compulsory with a statute in 1288, with the characteristic that they had to be built on private land but were for the public use of the citizens.
Moreover, Bologna's porticos have recently become a UNESCO heritage site.
