The Via Appia is the first and most important of the great roads built by the Ancient Romans, also known as "regina viarum" (or "queen of roads"). It was built in 312 BC to ensure swift and direct communication between Rome and Capua, an ancient town to the north of Naples. A revolution in road construction, the road was paved with close-fitting slabs of dressed basalt, ensuring it remained passable in all weather conditions, plus it was a public, toll-free road.
