An ancient Italian town, which disappeared after its abandonment 1,500 years ago and now lies buried underground, has been mapped by researchers, revealing the location of its theatre, marketplace and other buildings.
Originally founded as a Roman colony in the 4th century BCE, the site of Interamna Lirenas lies in the Liri Valley in Southern Lazio, about 50 miles south of Rome itself. After it was abandoned around the year 500 CE, it was scavenged for building materials and, over time, its remains were completely lost from view. Today, the site is an uninterrupted stretch of farmland, with no recognisable archaeological features.
