Carpenters Wow Public with Medieval Techniques at Notre Dame

Elaine Ganley, Associated Press, September 19, 2020

With precision and boundless energy, a team of carpenters used medieval techniques to raise up — by hand — a three-ton oak truss Saturday in front of Notre Dame Cathedral, a replica of the wooden structures that were consumed in the landmark’s devastating April 2019 fire that also toppled its spire.

The demonstration to mark European Heritage Days gave the hundreds of people a first-hand look at the rustic methods used 800 years ago to build the triangular frames in the nave of Notre Dame de Paris.


A debate over whether the new spire should have a futuristic design or whether the trusses should be made of fireproof cement like in the Cathedral of Nantes, which was destroyed in a 1972 fire, ended with the decision in July to respect Notre Dame’s original design and materials.


French President Emmanuel Macron wants the cathedral reopened in 2024 in time for the Paris Olympic Games, a deadline that many experts have called unrealistic.


The truss mounted for the weekend display is a replica of truss No. 7, more advanced that the first six trusses, which were “more primitive,” said Florian Carpentier, site manager for the team from Carpenters Without Borders team that felled the trees and used axes to cut the logs for the wooden frame. With rope cables and a rustic pulley system, the carpenters slowly pulled the truss they built in July from the ground where it was laid out.

“It’s a moment to see, ancestral techniques that last. There is the present and the past and it links us to our roots,” said Romain Greif, an architect who came with his family to watch the display. “It’s an event.”

In a final touch, once the No. 7 truss replica was raised on high, a carpenter shinnied up the wooden beams — to cheers — to tie an oak branch to the top of the triangular structure, a symbol of prosperity and a salute to the workers, a tradition still honoured in numerous European countries.
