Carpenters Wow Public with Medieval Techniques at Notre Dame Associated Press PARIS - 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 demonstration to mark European Heritage Days gave the hundreds of people a firsthand look at the rustic methods used 800 years ago to build the triangular frames in the nave of Notre Dame de Paris. It also showed that the decision to replicate the cathedral in its original form was the right one, said Gen. Jean-Louis Georgelin, who heads the cathedral's reconstruction. "It shows '¦ firstly that we made the right choice in choosing to rebuild the carpentry identically, in oak from France," Georgelin said in an interview. "Secondly, it shows us the ... method by which we will rebuild the framework, truss after truss." 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. .
