Support the restoration

Answers to the three key questions about the ongoing restoration campaign and its funding.

The public establishment has identified eleven operations that are essential to the cathedral's long-term preservation and complete restoration, bringing them together in a comprehensive Restoration Master Plan. Here are its main components.

The north and south rose windows are thirteenth-century masterpieces and rank among the world's finest ensembles of medieval stained glass. Weakened by time, weather, and pollution, they will undergo a major restoration campaign designed to preserve their artistic splendor, structural integrity, and brilliance for generations to come.

A major masterpiece of thirteenth-century Gothic architecture, the south façade of the transept of Notre-Dame de Paris features the south rose window and an exceptionally rich program of nineteenth-century sculptural decoration. A comprehensive restoration campaign is required to clean, consolidate, and, where necessary, restore this monumental ensemble, ensuring that it can be passed on intact to future generations.

The exterior elevations of Notre-Dame's nave, together with their flying buttresses and sculptural decoration, form one of the defining achievements of Gothic architecture, which has been weakened and damaged by centuries of exposure to the elements. The extensive restoration campaign now required will guarantee the cathedral's long-term structural stability while reinstating the richness of its heavily weathered sculptural decoration.

Overlooking the cathedral square and forming an essential part of Notre-Dame's iconic silhouette, the towers of the west façade remain in good condition on the square-facing side but bear the marks of time on their other elevations. They are also home to the celebrated chimeras created by the architect Eugène Viollet-le-Duc, which, like many of the façade's sculptural elements, have been severely damaged by weathering.  Their restoration, together with that of the gargoyles and numerous other decorative features, is now essential to ensure their long-term preservation. The roof of the North Tower must also be completely rebuilt.

Built in the nineteenth century in the style of a small medieval manor house, and listed as a Historic Monument since December 2024, the presbytery has never undergone major restoration. Masonry repairs are now required to ensure its long-term preservation while allowing it to continue serving the cathedral.
