Rome is a vibrant, populous and highly modern city. The sprawling and beautiful Italian capital stretches over an area of 58 square miles and has a population of roughly 3,800,000. The ‘eternal city’, which was left relatively untouched by the ravages of the Second World War, is crammed full of Renaissance and Baroque architecture. Vatican City – officially the smallest nation in the world – is an enclave of Rome.

The city is a place where the past meets the present on every road, as well as below them. A journey beneath Rome’s sophisticated sun drenched streets reveals a staggeringly interesting secret history. Infamous Roman emperors such as Caesar, Augustus and Nero, have each left their marks on the city - and left remnants of their reigns underground.

We join charismatic host Eric Geller on an amazing journey through the city’s subterranean past. He outlines the details of a secret cult that practiced next to the famous Circus Maximus, revealing a temple which still remains beneath the street.

Beneath the Piazza Navona, which sits majestically at the top of Domitian’s Stadium, pieces of the emperor Trajan’s Basilica can be found under a gallery owned by fashion dynasty, Fendi. Eric shows us that Rome’s underground is filled with evidence of life during the Empire. Our enthusiastic presenter discovers what life was like during Nero’s tyranny and Augustus’ reforms, peeling back the layers of time in order to display the subterranean secrets of the Roman Empire.
