POLICY WIRE — Paris, France — A newly uncovered ancient wall beneath a hotel in Paris has sparked excitement among historians and archaeologists, with officials calling it a potential breakthrough in understanding the city’s early history.

The structure, measuring approximately 65 feet long, was found this summer during excavations at the Hotel-Dieu on the Ile de la Cite, near Notre Dame Cathedral. Experts believe it could be part of the original ramparts of Lutetia, the ancient name for Paris, built by the Gallic Parisii tribe around the time of the Roman conquest.

Culture Minister Catherine Pegard called the discovery one of the most significant finds related to Gallic Lutetia, though she emphasized the need for further scientific analysis. The wall shows signs of fire damage, aligning with historical accounts that the Gauls burned their town before the Battle of Lutetia in 52 B.C., according to carbon dating that places the structure between 10 and 200 B.C.
