The restoration campaign and the preparatory work for the site were presented at a press conference on 14 March 2023. This restoration project in Auvergne-Rhône-Alpes is supported as part of the recovery plan.

Notre-Dame-de-l'Assomption Cathedral is a Gothic building built in 1248. It replaced a Romanesque cathedral located in the same location which itself had been preceded by two other Christian shrines. His initial patronage was that of Saint Vital and Saint Agricol. Most of the current construction dates from the second half of the 13th century. However, the western façade and the two adjacent bays of the nave were built on the project of the architect Eugene Viollet-le-Duc during the second half of the 19th century. The cathedral was classified as a historical monument in 1862. It has been state property since 1905.


Since 2017: a new dynamic, the project of restoration of the covers
In 2017, a new chief architect of historical monuments , Rémi Fromont, is appointed to conduct the studies and restoration work of the cathedral, under the project management of the Regional Directorate for Cultural Affairs Auvergne-Rhône-Alpes.
2017 to 2019, several studies are entrusted to him by the Regional Conservation of Historical Monuments (2017: survey of the cathedral/ 2018: evaluation study/ 2019: diagnosis of the enclosure and the cover, structural diagnosis and safety diagnosis), in order to establish health priorities and a multiannual programme of work.
From the end of 2019, security work is being carried out by the ACMH on the cover of the nave, in order to ensure its safeguarding pending the completion of the studies that must allow its complete restoration. In parallel and under the project management of the 'architect of the buildings of France , regular maintenance work is performed.
In September 2020, the study for the “removal” of the cathedral – identified as a priority issue – has been completed. It foresees an ambitious and necessary campaign of works, aimed at the rehabilitation of all the covers of the cathedral and the improvement of fire safety, in line with the new orientations of the safety plan for cathedrals put in place following the Notre-Dame de Paris fire of 15 and 16 April 2019.
2021 is dedicated to the development of the first phase of the lead roofing restoration project,
with the definition of the operating modes of intervention and the site installations. These studies, carried out in partnership with the Labour Inspectorate and with a specialised consultancy firm, have made it possible to define protocols in order to ensure, on the one hand, the working conditions of undertakings (protection of workers) and on the other hand the safety of the residents by guaranteeing the watertightness of the site.
2023 : start of a major construction site, restoration of the covers.


In total, a global project of an estimated amount of nearly 21.5 million euros, with a minimum duration of 6 years, will begin.


In view of the long temporality of this work, a reflection is undertaken in order to allow the launch of operations equally urgent to improve safety, in particular with regard to the fire regulations of the building, as required by the Ministry of Culture, as part of the action plan «safety cathedrals»
The challenge for the teams of the Drac and for the chief architect, is to reconcile this emergency work, therefore by definition unpredictable, with the consequent program of work planned, in a constrained schedule and budget.
