Adjacent to the Colosseum are the ruins of the Roman Forum and Palatine Hill. The Roman Forum was the hub of public life in ancient Rome, hosting political debates, public speeches, and grand processions. Palatine Hill, on the other hand, was the most desirable neighborhood in ancient Rome, home to emperors and aristocrats. These sites offer a fascinating glimpse into the daily life and political workings of ancient Rome. It's a beautiful exploration of Roman history.
