Orange Cathedral was consecrated in 1208. After being sacked by the Huguenots in 1561, it was restored in the early 17th century. It is entirely covered in painted decoration, some of which has already been restored.

The next part of the project concerned bays 2 and 3 of the church, i.e. the chapels of Saint-Joseph, the Sacred Heart, Sainte-Anne and the south entrance chapel. This project follows on from the studies and restoration work carried out by the City of Orange between 2016 et 2018 on the west bay of the church, the Baptismal Front chapel and the Saint-Antoine chapel.

A stratigraphy of the painted decorations was carried out in 2020 bye Claire Delhumeau, a painted decor restorer, and this assessment was supplemented by laboratory analyses following the sampling of salts in the entrance chapel. The state of health of the painted decorations thus completes the studies of the decorations carried out in 1993 by Le Centre Régional d'Etude et de Traitement d'Oeuvres d'art (C.R.E.T.O.A) and confirms the successive campaigns of decoration and their sate of conservation. The chapels are being restored on a case-by-case basis, while maintaining an overall view of the church.
