The Gallic Lutetia
  Possible locations of the oppidum
Possible locations of the oppidum
  Despite this lack of connection between historical and archaeological sources, we cannot rule out the possibility that the oppidum was on the Île de la Cité. There are several possible explanations for the lack of vestiges. The term "oppidum" could have been used to designate a fortification that may have been built only a short time before the Conquest. Any remaining traces of this may have been swept away by frequent flooding and by the extensive urban development of the island in the Early Roman Empire.

  Cependant, la recherche récente prouve que d'autres lieux dans la périphérie immédiate de la ville de Paris actuelle présentent une topographie coïncidant avec les sources et constituent d'excellents candidats à la Lutèce gauloise.

Other locations
t is quite possible that the oppidum that was destroyed was located on another island or peninsula that has since disappeared. Several sites in the Paris area correspond to Caesar's description:
· The space between the Seine's former branch on the right bank and its current location would have created a zone protected by marshland. However, this theory is not supported by any archaeological discovery.
· Some discoveries have been made on the Île Saint-Louis, but they are not well documented.
· A series of occupation layers dating from the Neolithic to the Roman era have been uncovered on the left bank at the level of the Sully bridge, but none of the discoveries indicates the nature of the Gallic-era occupation.

"A la recherche de l'oppidum perdu"
There is very little proof of a Gallic presence on the site of Paris at the time of the Gallic wars. We have yet to discover remains of the oppidum. We should not be surprised if Roman Lutetia was moved several kilometres from its protohistoric location, as this was common practice for the capitals of Gallic tribes. But such movements are usually accompanied by a name change. The fact that the name Lutetia was retained during the Roman period suggests that the Gallic oppidum is not far away.
