Undergound Perugia.
About
Undergound Perugia. The escalators from the lower town lead up through the remains of Rocca Paolina which was a 16th-century fortress. This was built on top of medieval streets, which were used as foundations, and before coming out into daylight at Piazza Italia you go through some of these medieval streets covered with brick ceilings when the fortress was built. Little now remains of the fortress itself.
