The rebuilding of Notre Dame Cathedral is on track, despite being set a challenging deadline of December 2024, just four years after a major fire caused €865m ($1.08bn) of damage to the structure. To ensure the Cathedral remains true to its original construction from 800 years ago, carpenters are deliberately using medieval tools, such as hand axes and mallets. While modern materials could speed up the work, organizers say historical accuracy is more important, commented a French project overseer. Some aspects of the project will be modernized, however, with computer analysis helping to ensure accurate measuring and correct assembly.
