The Appian Way is one of the earliest and most important Roman roads, constructed in 312 BC to connect Rome with Capua and later extended to Brindisi in southern Italy. Known as the "Queen of the Roads," it played a crucial role in Roman military and economic expansion. Today, parts of the ancient road remain paved with large basalt stones and are lined with archaeological ruins, including catacombs, tombs, and ancient villas, making it a popular site for history enthusiasts and cyclists.
