Archaeologists working in the forecourt of Notre-Dame Cathedral in Paris have uncovered Roman-era relics and medieval ruins beneath the city square [1].
The discovery provides a rare glimpse into the urban evolution of Paris. By documenting these layers, researchers can map the transition from a Roman settlement to a medieval powerhouse before the site is repurposed for modern use.
The excavation has reached a depth of four meters [1]. At these levels, teams have found evidence of the city's earliest inhabitants. While some reports indicate the oldest layers are approximately 1,700 years old [2], other estimates suggest the findings date back as far as 2,000 years to the era of Roman Paris [3].
This archaeological effort is not a standalone project but part of a larger city initiative. Paris officials said they are working to transform the area into a greener public square [1]. The project aims to integrate environmental sustainability with the preservation of the site's deep historical record.
Work at the site will continue as the city documents the remaining archaeological layers. The excavation and subsequent redevelopment of the forecourt are scheduled for completion by 2028 [1].
“Archaeologists have uncovered Roman-era relics and medieval ruins beneath the square.”
The discovery highlights the intersection of urban modernization and historical preservation. By conducting these digs during the transition to a greener public space, Paris is utilizing infrastructure projects to recover lost data about the city's Roman foundations, ensuring that the 2028 redevelopment is informed by the site's 2,000-year trajectory.
