Gallic Wall of Lyon
The Gallic Wall of Lyon is a Gaulish wall discovered on the southwest plateau of Fourvière (Lyon) during preventive excavations conducted in 2014 at Abbé-Larue Square. Its construction is estimated to date back to the first half of the 1st century BCE. A diagnostic conducted in 2012 revealed several elements of the fortifications that marked the local history: a Roman rampart, the Retraite enclosure (14th century), and the Fourvière enclosure (19th century).
