 | Falerii Novi was a walled city spanning 30.5 hectares about 50km north of Rome. It was founded in 241 BC and was inhabited until around 700 AD. This is the first time a complete ancient city was mapped using ground-penetrating radar. With a population of 3000 people, it boasted an elaborate public bath complex and market building, and at least 60 large houses.  |
 |  One notable discovery was the location of the city’s water system. GPR showed it was laid out underneath the buildings before they were built, suggesting the city's construction was highly planned. |
