“Merci” is the motto at the <a href="https://www.facebook.com/groups/tailleurdepierre"target="_blank">Tailleur de Pierre</a>  stonemasonry group at Facebook: ”Thank you to our colleagues on the construction site. Thank you to the partners. Thank you to the institution Rebâtir Notre-Dame de Paris” (Rebuild Notre-Dame).

In an unprecedented effort, the nation has restored the cathedral / Numerous findings on the construction methods around 1160

Notre-Dame de Paris will reopen on December 07 and 08, 2024. In an unprecedented effort, the French have secured the building, recorded the damage, cleaned it of pollutants, and finally restored it in just 5.5 years since the fire on the night of April 16, 2019.

There is talk everywhere of an “extraordinary mobilization” in the country.

The mood shortly after the disaster can be captured by a report from the French trade magazine Pierre Actual: “Around April 28, 2019, on a Sunday afternoon a few days after the fire, an email spread through the French restorers’ networks: ,We have to be in Paris tomorrow to assemble teams of stonemasons for Notre-Dame‘ … After a short night, a number of experts for stone-restoration were on site. So that the entire stone sector would not immediately set out, the circular had been limited to the circle of real experts“ (see link below).

As far as replacing the – fortunately few – totally damaged limestones was concerned, the first step was to find quarries with the right material. “They are not the original quarries, but they are all located in the basin of Lutétien, where the stones had been extracted before,” we wrote in a report. Then the best raw blocks were selected and cut to size for the new use.

Note: the approx. 1000 m³ of limestone required is not much compared to the total amount in the walls, but is far beyond the usual quantity needed for a restoration.

The provision of the oak beams, some of which were more than 20 m long, for the restoration of La Flèche was also spectacular.

We have linked to a few interesting sources, such as the research work carried out parallel to the reconstruction, the role of the digital duplicate, or the course of the work.
