The Appian Way was an ancient Roman road that connected Rome to the southern part of Italy. It was constructed in 312 BC by Appius Claudius Caecus and was the first major Roman road built. The Appian Way was used for centuries as a major trade route and was known for its impressive engineering feats, such as the construction of bridges and aqueducts. It was also used by Roman armies to march to battle. The Appian Way is still visible today and is considered one of the most important Roman roads ever built.
