Since the ancient times, people have sought refuge in underground, hidden from the eyes to escape the enemy, or to shelter from the weather, or to rest their dead. So if there were human settlements there are certainly places underground.

Above the ruins has been built several times, layer by layer. Some of these places can be visited, others only explored with specific techniques and equipment, others, perhaps most, are not yet known. And those detected are often unknown also to the Romans.
