With precision and boundless energy, a team of carpenters used medieval techniques to raise up — by hand — a 3-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 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.
