Works have re-started in Paris’ fire-ravaged Notre Dame cathedral after a hiatus linked to the coronavirus pandemic.

On Monday morning operations recommenced to dismantle scaffolding that was already in place before the April 2019 fire amid previous restoration efforts on the old structures.

This current phase of works has been deemed highly dangerous because the scaffolding weighs over 200 tons, and is thought to have melted together in areas because of the heat of the blaze.

The work will last through the summer months.

The imposing tower of scaffolding was erected before the blaze for the restoration of Notre Dame's spire that was then toppled and destroyed by the flames.

Teams have spent months consolidating the structure with metal girders so it can be dismantled without collapsing.

The cathedral is still closed, and will be for several years during renovations.
