Celtic road network

Timeline

1. c. -400–-250Central Gaul corridor · GaulArchaeological and place-name studies show that Celtic peoples opened land routes along river valleys and mountain passes connecting oppida (fortified settlements), with road surfaces often paved with timber, rubble, or rammed earth to cope with seasonal mud.
2. c. -200–-58Gaul throughout · GaulCaesar's accounts of his campaigns in Gaul and archaeological evidence indicate that the Celtic road network supported the mustering of tribal coalitions, chariot movements, and the transport of bulk goods such as salt and metals; fords and bridges became strategic points.
3. c. -50–1Southern Gaul—Rhône corridor · GaulAfter the Roman conquest was completed, large-scale construction of Roman roads began in the Augustan period, and many Celtic roads were incorporated into the imperial road network or abandoned; before this, the network remained a key transport foundation for Gaulish social integration and the Roman advance.
