Using extensive state-of-the-art CGI animation this documentary chronicles the spectacular as well as sordid history of the Roman Empire from the rise of Julius Caesar in 55 BC to its fall around 537 AD. The CGI animation gives the viewers an opportunity to see Rome's greatest structures the way the ancient Romans saw them. The insights of engineers, archaeologists and historians add depth to segments on Hadrian's Wall, Caesar's Bridge, the aqueducts, the Colosseum, the Pantheon, the Baths of Caracalla, and the remains of Emperor Nero's lavish Golden Palace for a rare look at how one of Rome's most notorious megalomaniacs lived. Also never-before-seen footage shot on a diving expedition in the water channels underneath the Colosseum, channels once used to flood the arena for mock naval battles.
