Porta Capena

Porta Capena marks the western end of the ancient Via Appia, the legendary road that once connected Rome to Brindisi in the southern heel of Italy. Alongside the Old Center and the Vatican, this area is recognized as one of three World Heritage Sites in Rome. While the remains of the original gate no longer command the attention of some of the city’s grander ruins, the spot holds great historical value.

Walking the Ancient Via Appia

As the Via Appia leaves the busy center of Rome and travels southeast, it eventually takes on the name Via Appia Antica. Here, the atmosphere begins to change. The wide modern street narrows, and city traffic gives way to the quiet of cobbled stones underfoot. Asphalt disappears, replaced by the original rock surface that has lasted through ages.

On both sides of the road, greenery takes over. Parks and gardens line the way, and centuries-old walls rise behind clusters of trees. Old buildings stand quietly, hinting at the many travelers who have passed through this historic corridor. This stretch of road is often called the world’s longest museum, where ancient history and nature come together just outside the heart of Rome.
