(CNN) — Archaeologists found an ancient lead sarcophagus under the cathedral of Our Ladyalong with fragments of a screen from the chancel, offering a new insight into the history of the building, currently under reconstruction following the devastating fire in 2019.
Dating from the 12th century, Notre Dame Cathedral commissioned excavation work inside the cathedral as a precautionary measure before the installation of scaffolding needed to restore a 100-meter-high wooden ridge cap.
“The floor of the transept has revealed remains of remarkable scientific quality,” said French Culture Minister Roselyne Bachelot, adding that the excavation work will last until March 25.
The excavation site is under a stony layer dating back to the 18th century, but some lower levels date back to the 14th century, and some even to the early 13th century, the culture ministry said.
Christophe Besnier of the National Archaeological Institute of France, said: “We were able to send a small camera inside which showed remains of cloth, organic matter such as hair and plant remains.”
“The fact that these plants are still there indicates that the content has been very well preserved.”
Archaeologists maintain that the lead sarcophagus likely belonged to a high-ranking dignitary and said it might date to the 14th century, which, if confirmed, would make it an incredible find.
The excavation also revealed a pit immediately below the cathedral floor, which was probably built around 1230, at the time of the cathedral’s construction, one of the earliest examples of French Gothic.
The Notre Dame fire shocked France, with Parisians crying and tourists watching in disbelief as the fire brought down the cathedral’s spire.
