In 1992, Atelier Boisseau-Cattiaux, in cooperation with Orgues Michel Giroud and Orgues Philippe Emeriau, completed restoration of the great organ at Cathédrale Notre Dame de Paris.
This organ of 110 ranks – more than 8,000 pipes – took 3 years to restore.
Except for the case, the large front pipes and the main bellows, all parts of the organ were taken to Mr. Cattiaux's workshop for restoration.
