Stonemasons have inherited their expertise from their cathedral-building forerunners. They master all aspects of working with stone, from its properties and the techniques used to shape it, to the assembly of the finished blocks. They intervene in all stages of the transformation of stone blocks.

For the restoration of historic monuments, stonemasons reinforce the solidity of stone blocks, replace damaged elements and carve gargoyles, rose windows and statues. They work directly with the sculpture restorers to clean old and damaged stone elements.

The stonemason's traditional know-how is complemented by the latest technological developments, being called upon to work with lasers and 3D software, for example.

 

On the Notre-Dame de Paris site

Immediately after the fire, stonemasons removed any stones that were likely to fall near the cathedral, along with the most fragile sculpted elements.

During the securing phase, they consolidated the flame-damaged structures (bracing of two pillars, reinforcement of gables) and helped clear away any stones that had fallen on the vaults and inside the cathedral.

During the restoration phase, stonemasons are intervening inside the cathedral and in the workshops. Inside the building, they are conducting desalination operations designed to restore the integrity of all the stone blocks, and participating in the cleaning of all walls, vaults and columns of Notre-Dame, notably using a latex-based technique. At the same time, they are working in workshops cutting the blocks of stone to be installed in the cathedral, while consolidating fire-damaged masonry and rebuilding the collapsed vaults.

 

How to become a stonemason? 

Training is can begin as early as the 8th grade, with a certificate of professional competency (CAP) specializing in “Stonemasonry” or "Stone-Working Trades". Trainees hoping to work on historic monuments are advised to undergo additional training and obtain a professional diploma (BP) in "Stonemasonry for Historic Monuments" or "Stone-Working Trades".

The three-year vocational baccalaureate in "Artistic and Craft Trades, Specializing in the Art of Stone-Working” or "Stone-Working Arts and Crafts" provides similar training.
