After you've finished the museum you'll no doubt want to wander out to the fort made in the Roman style.
It was a series of these forts that Caesar built that surrounded the Gauls; reports vary between 80,000 to hundreds of thousands that were surrounded. Through the necessity of having to space them out the Gauls actually managed to send for help but, ultimately, despite being attacked from both sides, the Romans prevailed and the first seriously major battle in France was won.
The fort shows how much engineering and thought went into these wooden structures. They must have spent a considerable time felling trees to make all the barriers that they put around the Gauls on the Oppidum. The line of forts went for 14-16 kilometres; there is a little uncertainty there, but they consisted of two or three trenches, a glacis equipped with a trap and a rampart.
This battle was after encounters in Gourges and Gergovia where eventually Caesar pressed his advantage utlilizing superior military hardware and discipline.
It is fair to suggest that the Romans would not have won had it not been for the support of German tribes, a fact that was acknowledged by Caesar.
Alliances such as these were part of the reason for the Romans dominance. Obviously the Romans had better technical weapons overall and were organized with a regular army constantly available.
The Gallic name of the oppidum was Alisiia and an inscription "in Alisiia" in the Gallic language was found in 1839 on Mount Auxois. It was the dedication of a building located to the north of the forum of the Gallo-Roma town.
The amount of equipment found in the area 2,000 years later is staggering; in fact, the biggest arsenal of Roman and Celtic weapons ever found comes from this very site and includes several hundred helmets, daggers, shields and swords along with thrown weapons, arrows, catapult bolts, slingshot and bullets.
Apart from these, tent leather (from a legionary's tent), hundreds of Roman sandal nails and other bits and pieces have been unearthed.
Two defining finds have been slingshots with the inscription T. LABI. which clearly identifies this as the camp of Titus Labienus, Caesar's chief lieutenant.
