A 10-year collaboration between UCLA, the University of Virginia and the Politecnico de Milano produced Rome Reborn 1.0, a virtual 3D model of the ancient city as it looked on June 21, 320 A.D.
The researchers studied information on Rome's topography, urban infrastructure, buildings and monuments, then filled in the rest using digital reconstructions.
If Google had been around in 4th century Rome, this is what the city would have looked like on Google Maps.
