SUMMARY
This contribution wants to show the history of the Archivio Arcivescovile in Bologna also to an untrained public: the numerous, important documents that it contains, the people who worked on it, the changes of seat that took place over the centuries. In this way, introducing the many funds now preserved, a history very linked to the Bolognese territory is rediscovered: in fact ancient and recent papers housed in this place often transmit unexpected, surprising information and contribute to a deeper knowledge of many places (sacred and profane) that cheer the gaze of the yesterday and today traveller.
