RENOVATION OF THE CHAPEL

WHY RENOVATION WORK ON THE CHAPEL ?

The Chapel of Notre-Dame du Haut by Le Corbusier, inaugurated on the 25th June 1955, has not undergone the appropriate repair of the concrete used in the middle of the last century, which has been damaged over time.

All buildings need permanent maintenance according to the evolution of their materials over time.

Various kinds of deterioration include :

Surface scaling : the surface mortar flakes off as a result of the corrosion of steel reinforcing.

Structural cracks are due to chemical reactions inside the materials used in the concrete mix or poor construction practices.
The Southern façade was made by projecting concrete on an iron framework. This technique was quite new at the time. It requires a deep
understanding of how the concrete will react over time to the thermal stresses caused by extreme seasonal temperature variations.

Watertight integrity needs to be monitored at all times. The contact between different materials causes joints to be fragile.

The window panes are also fragile elements. The various glass types, the cold or hot technique used for the writings and drawings account for this fragility. They are also vulnerable to vandalism or accidents.

The building was repainted regularly until 1995.

As a consequence, the roughcast has been overloaded with paint and needs to be cleansed before receiving the matt white coating originally provided by whitewash.

The buildings

The renovation work will deal with the three main buildings of the site: the Chapel of Notre-Dame du Haut, the Pilgrim’s Shelter and the Chaplain’s House.
The Chapel was listed as Historical Monument only twelve years after it was built, on the 8th November 1967. The two adjacent buildings were listed as Historical Monuments on the 11th June 2004.


A first study made in July 2011 enabled to assess the cost of the renovation of the three buildings.
In January 2015, a series of studies examined the different techniques to cleanse the facing and to open the cracks, they identified the
repair materials and studied how to protect the window panes. They made it possible to find renovation methods.

The renovation schedule is divided into five parts: 1 firm part and 4 optional parts.

The firm part
Until October 2021

The firm part will mostly deal with renovating the Southern façade and the underpart of the hull of the roof. This renovation will start with the topographical plan of the volume of the building and the precise mapping out of the cracks. The assessment of the experiments which have taken place since 2015 will enable to validate or change the repair methods.
Later on, the cracks and the oxidized iron mesh will be treated. Watertightness will be restored and reinforced. The facing will also be treated and painted to be more consistent with the original appearance.
It is to be noted that this part of the works will protect the Pilgrim’s Shelter and the Chaplain’s House, which are scheduled to undergo later renovation work.

Optional part 1
From November 2021 to July 2022
The Western and Northern façades as well as the turrets will be renovated. Cleansing, repair of the cracks, restoration of the watertightness of the window panes, painting.

Optional part 2
From August 2022 to June 2023
Renovation of the Eastern façade and of the South-West tower, repair of the large crack.

Optional part 3
From July 2023 to January 2024
