A 20 metre stone and timber wall is up under the Hôtel-Dieu

A stone-and-timber wall about 20 metres long has come up in a courtyard of the Hôtel-Dieu on the Île de la Cité in Paris. Carbon-14 dates the wood between 200 and 10 BCE. The culture ministry says the fire traces do not by themselves lock the blaze to 52 BCE, while the stretch is a candidate for the rampart of Gallic Lutetia and a rival reading still places that settlement at Nanterre.

Twenty metres of wall in the hospital courtyard

France's culture ministry reports a stone-and-timber wall of about 20 metres in a courtyard of the Hôtel-Dieu on the Île de la Cité. Carbon-14 dates the wood between 200 and 10 BCE. The Guardian's 23 September report describes the same stretch, about 20 metres under a building on the island near Notre Dame. It calls the structure stone and wood and links it to the rampart of Lutetia, the name the Parisii used for the settlement. Both accounts put the find on the island in the centre of Paris, at the hospital, and both give the length as about 20 metres.[1], [2]

The fire traces stay inside a wide carbon range

The ministry says the building method matches Gallic fortifications from the end of the Iron Age, with an artificial platform of sand and gravel on the inner side of the wall. It also says the fire traces alone do not lock the blaze to 52 BCE. The carbon range of 200 to 10 BCE can include that year and can sit earlier or later inside the same span. The Guardian reports culture minister Catherine Pégard describing the remains as among the most important yet for understanding Gallic Lutetia, and it records the rival reading that the original settlement stood at Nanterre, west of the island. The ministry's measured range is the date. The 52 BCE battle is still a hypothesis sitting inside that range.[1], [2]

A candidate rampart, with Nanterre still in the argument

The ministry treats the wall as a possible piece of the Parisii oppidum rampart, the fortified settlement Caesar described, and says a confirmed identification would tie today's Paris, Roman Lutetia and that Gallic town in one place on the Île de la Cité. The Guardian reports the same possibility and the same caution in the ministry's public wording: the wall could confirm the site of the first settlement, and the Île de la Cité has been the traditional centre, against the Nanterre alternative. Neither account publishes a closed proof that the burned timber is the 52 BCE fire. What both publish is the 20 metre stone-and-timber wall, the late Iron Age construction, and an open argument between the island and Nanterre.[1], [2]
