The operation to shore up fire-ravaged Notre-Dame Cathedral is entering a risky stage as engineers resume preparations for the removal of scaffolding that could provoke a further collapse.
The
Paris landmark lost its roof and spire in the April 15 blaze, but the main bell towers, outer walls and much of the vaulted ceiling survived, along with religious relics and artworks.
Starting in February, their first delicate task will be the removal of 250 tonnes of damaged scaffolding installed for a renovation planned before the
fire, without it falling onto the medieval vaulting.
