Archaeologists have discovered an ancient coffin under the Notre Dame Cathedral in Paris.
The lead coffin, also known as a sarcophagus, was uncovered along with several ancient tombs.
France's Culture Ministry said some lower levels of the excavation site are believed to date back to the 14th century.
It said the unearthed burial sites represented "remarkable scientific quality."
Among the discovered tombs was the "completely preserved, human-shaped sarcophagus made of lead," the ministry added.
Archaeologists said the coffin may have been created for a high-level official who had lived at the time.
The excavation work is happening as workers repair the historic religious center after a destructive fire in 2019.
Because of the latest discoveries, officials decided to extend the excavation work until March 25.
Christophe Besnier is with France's National Archaeological Institute.
He told Reuters his organization was able to send a camera down to where the work is being done.
It captured materials including cloth, as well as remains of hair and plants.
"The fact that these plants are still there indicates that the contents have been very well preserved," he said.
In addition to the tombs, elements of painted sculptures were also found just beneath the current floor level of the cathedral.
Other ancient materials were unearthed during repairs carried out at Notre Dame in the mid-1800s.
Many of those pieces are included in the collection of the Louvre museum in Paris.
