The rampart rests on a bank of earth and stones, reinforced on the inside by a network of wooden beams assembled at right angles with long iron nails measuring 20 to 30 centimeters. The whole is preceded by a ditch, the \u003Cem>vallum\u003C/em>, sometimes several dozen meters wide, and its facade is covered with a dry-stone facing. This hybrid design proved remarkably effective: the wood absorbed the impact of battering rams without breaking, while the stone prevented fire from spreading inside the rampart.\u003C/p>\n\u003Chr>\n\u003Ch2>🏛️ Bibracte, a reference oppidum\u003C/h2>\n\u003Cp>The oppidum of \u003Cstrong>Mont Beuvray\u003C/strong>, in Saône-et-Loire, better known as \u003Cstrong>Bibracte\u003C/strong>, offers the best-documented example of this architecture. Founded toward the end of the \u003Cstrong>2nd century BCE\u003C/strong>, the site had two successive enclosures: a vast outer enclosure of about 200 hectares, then an inner enclosure reduced to 135 hectares. Its ramparts, of the Murus Gallicus type, underwent at least five rounds of reconstruction for the inner enclosure alone — proof of constant upkeep and dense occupation across several generations.\u003C/p>\n\u003Chr>\n\u003Ch2>⛰️ Gergovie, an exception\u003C/h2>\n\u003Cp>Not all oppida, however, followed this same model.

A recent study even detects a Hellenistic architectural influence there, of the type known as a “spurred wall” — a sign that Gallic builders did not simply reproduce a single technique, but adapted their fortifications to local resources and, at times, to models arriving from the Mediterranean.\u003C/p>\n\u003Chr>\n\u003Ch2>🧠 Key points\u003C/h2>\n\u003Cul>\n\u003Cli>Oppida are fortified hilltop towns specific to the very end of the Iron Age, well after the period covered in the main chapter (~600 BCE).\u003C/li>\n\u003Cli>The Murus Gallicus combines nailed wooden beams, earth, stone, and a dry-stone facing — a technique effective enough to impress Julius Caesar.\u003C/li>\n\u003Cli>Bibracte (Mont Beuvray), founded toward the end of the 2nd century BCE, illustrates this model with its two successive enclosures.\u003C/li>\n\u003Cli>Gergovie, with its dry-stone rampart of possibly Hellenistic inspiration, shows that this model was not the only one.\u003C/li>\n\u003C/ul>\n",true,false,"The phenomenon of the oppida (singular: oppidum ) does not belong to the period covered in the main chapter: far from the dawn of Hallstatt, which closes",1786625672469]
