Guida per camminare all'ombra: The documentary illustrates the history of the birth and development of the porticoes module in Bologna, starting from the Middle Ages. After a brief historical investigation on the origin of the arcades and on the revolution that affected urban architecture following their introduction, we analyze the social impact that these had, and still have, on the lives of Bolognese citizens. The porch, among other things, is presented as an architectural solution capable of facilitating meeting and communication.
