Hidden city beneath notre dame: archaeologists unearth 2,000 years of parisian history
As tourists craned their necks to glimpse the gargoyles of Notre Dame, a secret excavation was unfolding just four meters below – a relentless journey back to Roman Paris.
A century of secrets revealed
The cathedral’s recent reopening marked a symbolic moment for Paris, but beneath the tourist crowds, a team of archaeologists was rewriting the city’s history. This isn’t just restoration; it’s a discovery of staggering proportions – a ‘dig of the century,’ as one French media outlet dubbed it.
The painstaking work, necessitated by the need to safeguard the site’s foundations, has unearthed layers of Parisian life, from the fourth-century Roman quarter to the medieval houses that once lined the square. Each day, crates overflowing with artifacts – coins, pottery shards, and even remarkably preserved everyday objects – are painstakingly hauled to the city’s archaeology center.

Lost worlds, found objects
Among the treasures recovered, a fourth-century coin bearing the likeness of Emperor Constantine stood out, alongside enigmatic markings on medieval pottery that have baffled experts. “It’s like a modern Da Vinci Code,” remarked conservator Lucie Altenburg, highlighting the tantalizing mystery surrounding these ancient inscriptions.
The finds extend far deeper than the cathedral itself. Merovingian and Carolingian grain pits, dating back to the sixth and tenth centuries, were discovered, followed by a dense Roman settlement from the fourth and fifth. Archaeologists estimate they’ve penetrated approximately 4 meters – equivalent to the height of two and a half Napoleons stacked on top of one another – revealing a remarkable vertical timeline of Parisian evolution.

More than just a landmark
“Here you can see the layers – medieval Paris, Roman Paris, maybe even before that,” explained Yasmine Benali, an archaeology student observing the dig. “It makes the city feel less like a postcard and more like something still being discovered.”
Surprisingly, the most compelling discoveries have originated from the foulest of places: the submerged cellars beneath the medieval houses – former latrines that served as dumping grounds. Among the debris, archaeologists have unearthed complete jugs, cups, and plates, remarkably intact after centuries of submersion. These objects, protected by the soft waste, offer a poignant glimpse into the daily lives of Parisians long ago. Valentine Breloux, an archaeologist, noted that finding complete ceramics is
