Gallo-Roman wall found beneath Paris hospital

The discovery on Île de la Cité could provide new clues about the origins of Lutetia.

Archaeologists have found a wall of stone and wood beneath the Hôtel-Dieu in Paris that may have formed part of a Gallic fortification. The French Ministry of Culture has called the discovery important, but its interpretation is not yet definitive.

The wall was found on Île de la Cité, the island in the Seine where Notre-Dame also stands. The excavations are taking place in two courtyards of the Hôtel-Dieu as part of the redevelopment of the hospital complex.

According to the French Ministry of Culture, the structure has been preserved over a distance of approximately 20 metres. The combination of stone and wood, together with the construction technique, is consistent, according to the archaeologists, with fortifications from the late Iron Age, the period before Gaul was fully incorporated into the Roman Empire.

A Gallic spearhead was also found beside the wall. The object supports the dating and interpretation, but in itself it does not constitute conclusive evidence that the wall marked the boundary of the settlement of Lutetia described by Julius Caesar. Further analysis and comparison with other finds are needed for that.

The location of the original settlement of the Parisii, the Gallic tribe from which Paris takes its name, has long been the subject of archaeological debate. Île de la Cité is regarded as an important candidate, but researchers have also pointed to settlement elsewhere in the area around the Seine.

The excavation has been carried out since February by the archaeological service of the city of Paris and the Institut national de recherches archéologiques préventives, under the scientific and technical supervision of the French Ministry of Culture. The researchers still have to document and date the structure and study it in relation to its surroundings.

The announcement is an institutional press release about an ongoing excavation, not a completed scientific article subject to independent peer review. The discovery may increase knowledge of early Paris, but the wall’s precise function and its significance for the city’s origins remain open for the time being.

Editor's note
The wall, its location, length and the archaeological institutions involved have been confirmed. The link with the original settlement of Lutetia is a research hypothesis, not yet an established result.
