After leaving the Colosseum and Arch of Constantine, you will see signs directing you to the Roman Forum along Via Sacra. The Sacred Road was constructed before the 5th century BC. This colonnade is considerably younger. It was added during the reign of Roman Emperor Nero during the middle of the 1st century AD. Just imagine the centuries of Roman citizens, dignitaries, political leaders and victorious warriors who took this path to the geographical heart of ancient Rome.
