New map reveals lost roads of the Roman Empire
A new high-resolution map has been created to reveal the extensive network of Roman roads, nearly doubling the previously known length. This project combines historical data with modern technology to provide a clearer understanding of how these roads facilitated the Roman Empire's expansion and administration. Despite this advancement, only a small fraction of the road network's precise locations are currently known.
- ▪The new map indicates that the Roman road network comprised approximately 300,000 kilometers at its peak.
- ▪This is nearly double the previously known total length of Roman roads.
- ▪The research highlights that only 2.7 percent of the road network's precise locations are currently identified.
