Falerii Novi: Buried Roman city mapped out in stunning images using sophisticated radar

Ground Penetrating Radar (GPR) is a technology that has long been used to map out what's beneath the ground. The benefit of this technology is that it does not damage any artifacts that might be there in the area being surveyed. In the latest discovery, an ancient Roman city has been found underground without overturning a single grain of soil. This has been done using GPR technology.
