Archaeology
From the early Villanovian settlements, to the Etruscan "Felsina", or to the Roman "Bononia"... Though sometimes they are not accessible to visitors (for instance the ruins of the Roman Theatre in Via Carbonesi not open to the public), many traces of the ancient Bologna speak of the city history through centuries. A history that is also revealed in important sites located in the surroundings, such as in Marzabotto, Castenaso, Monterenzio, San Lazzaro, Ozzano and in many other places of the province.
Archaeological excavations in Salaborsa
In the library Salaborsa, under the crystal floor of the covered square, a suspended platform guides the visitor along a fascinating and stimulating stroll through history.
Roman bridge Torrente Aposa
7,500 meters long, the Torrente Aposa is the only natural river in Bologna. It originates in the hills and empties into canale Navile. Under Via Rizzoli there is a splendid ruin of Roman bridge (not accessible at the moment).
