In 2019, a fire broke out inside Notre Dame Cathedral in Paris, severely damaging the iconic medieval building. However, the catastrophic fire gave researchers an opportunity to study the building’s architecture like never before.
A few months after the inferno was extinguished, researchers discovered that the stones used to build the Gothic-style cathedral were held together using iron staples, a technique that had never been documented before in a building from this time period, according to a study published March 15 in the journal PLOS One (opens in new tab) .
Notre Dame was constructed in multiple phases starting in the early 12th century and continuing for the next 300 years, according to the Notre Dame Cathedral website (opens in new tab) .
“This is the first building of its kind in which we see this,” lead author Maxime L’Héritier (opens in new tab) , a professor in the Department of History at Paris 8 University, told Live Science. “This shows [that the builders] at the time were trying to experiment with new forms of construction.”
L’Héritier and his team analyzed 12 of the iron staples, which measure approximately 20 inches (50 centimeters) long and were part of the “iron skeleton” holding the building together, L’Héritier wrote in an essay for the archaeology publication Sapiens (opens in new tab) .
The staples offered additional reinforcements to the cathedral’s stonework, including holding together the large arches in the nave of the building’s towering 226-foot-tall (69 meters) twin towers. Without the staples’ support, this architectural feat would likely have been impossible to accomplish in 1160, when construction of the building began, according to the study.
“When we studied other Gothic churches of that time period, none used iron in their construction,” L’Héritier said. “We believe that the staples were what enabled them to build this structure at such a terrific height.”

Researchers radiocarbon dated the iron staples and discovered that they were used during one of the initial construction phases, “confirming that the production date of the staples was the same as the masonry, which also dated to around 1160,” L’Héritier said.
However, L’Héritier cautioned that it will take further analysis to know the iron’s exact origins.RELATED STORIES—14th-century sarcophagus found at fire-ravaged Notre Dame Cathedral

“We’re trying to figure out if it’s local or more distant,” L’Héritier said. “There also seems to be different ore sources depending on whether the construction occurred in the 12th or 13th centuries. We do know that the [cathedral’s] bishop died at the end of the 12th century, so it’s possible that a new ore resource was used years later. We should know more in a year or two.”
In the four years following the blaze, Notre Dame has been undergoing reconstruction and is expected to reopen to visitors in December 2024, according to AP News (opens in new tab) .
YouTuber-turned-boxer Jake Paul has defeated one of the greatest-ever fighters, former heavyweight world champion Mike Tyson, who’s more than twice his age.
The bout was won on a unanimous points decision at the AT&T Stadium in Arlington, Texas – home of the Dallas Cowboys and the biggest NFL stadium in the US.
The fight was already controversial but then arguably failed to live up to the hype. Boos were heard from the crowd in the final two rounds, after a perceived lack of action.
Boxing careers compared
This was not Paul’s first professional fight. The 27-year-old American YouTube star made his debut in 2020 with his most high-profile clash against Tyson Fury’s brother Tommy Fury last year, which he lost by a split decision.
The so-called “Problem Child” has since defeated former UFC contender Nate Diaz, professional boxer Andre August, former Gold Gloves champion Ryan Bourland and most recently MMA fighter Mike Perry.
In contrast, “Iron Mike” Tyson, 58, was ranked among the best heavyweight boxers of all time.

He returned to the ring in 2020 for a bout against fellow boxing icon Roy Jones, which ended in an unofficial draw.

‘Someone’s getting put to sleep’
Earlier this week, Paul said he believed the bout would not go the distance. “No, someone’s getting put to sleep,” he said. “It’s going to be a war, and we’re both heavy hitters. It’s not going the full 16 minutes.”
Tyson was more reflective: “I’ve been through so many ups and downs since my last fight with Kevin McBride,” he said.
“I’ve been in rehab. I’ve been in prison, been locked up. Never in a million years did I believe I’d be doing this.”
Several states would not allow the bout to go ahead, and the Texas Athletic Commission only agreed to the fight if there were changes, due to Tyson’s age.
It limited the contest to eight rounds lasting a maximum of two minutes instead of three. Both boxers were also required to wear heavier gloves, designed to lessen the force of punches.
The fight was initially scheduled for 20 July, but was postponed when Tyson suffered an ulcer flareup.
Taylor defends title
Meanwhile, among the undercard fights, Irish boxer Katie Taylor successfully defended her super lightweight world title against Puerto Rico’s Amanda Serrano.
But it was tight. Taylor claimed the rematch 95-94 for all three judges in an epic battle.
The bout came two and a half years after the pair fought at Madison Square Garden, which Taylor won on a split decision.
Bout suffered from buffering
Earlier in the evening thousands of Netflix users in the US reported problems seeing the coverage, with some posting on social media about buffering.
At one point, more than 98,000 people had reported issues according to Downdetector, which tracks outages.
