Paris: Massive oak trusses were spectacularly lifted from a barge onto Notre Dame Cathedral on Tuesday in an effort to reconstruct the destroyed structure and bring it back to life by December 2024. Crowds gathered along a bridge over the Seine River and on its banks to watch the delicate operation, which involved trusses weighing 7 to 7.5 tonnes. The Seine will be at the centre of the Paris Olympic Games in 2024, said Transport Minister Clement Beaune. "I think it's a magical moment for a lot of Parisians this morning," he added.

They were being installed on the roof near the iconic spire, which burned to cinders, and the two arms of the transept, the wooden skeleton of Notre Dame. They were being held in place by ropes. According to a statement, as work progresses, the silhouette of Notre Dame, which is currently engulfed in scaffolding, should become more visible on the skyline.
