FRANCE. PARIS, 10 december 2019. Notre-Dame de Paris' cathedral. The huge scaffolding which was set up to restaure the spire has burnt in particular in the middle. The challenge is to remove each pieces of the 25000 iron tubes without making the whole thing falling down which could break an arch. Here, the scaffolding seen from the north with workers setting up new tubes all around in order to reinforce the old one.
