Step back in time at Porta Maggiore, a powerful remnant of Bologna's medieval city walls. Once a grand eastern entrance along the ancient Roman road, Via Emilia, this 13th-century gate welcomed popes and sovereigns. Though now standing as a proud, roofless structure with its distinctive pointed arches, it's easy to imagine its former glory. You'll find it at a bustling intersection, a striking piece of living history that marks the edge of the historic center.
