The Arco del Meloncello is an 18th-century Rococo structure in Bologna, that forms a pedestrian portico over the road (hence an arch); it is part of the Portico di San Luca, a long arcade that sheltered the walk from the Cathedral of Bologna to the hillside Sanctuary of San Luca, Bologna. It lies beyond the gates of the Porta Saragozza, outside the former city walls of Bologna. Read more on Wikipedia
