About Basilique du Sacré-Cœur

📜 History

The Basilica of the Sacred Heart has its origins in the years following the Franco-Prussian War. On September 4, 1870, Bishop Félix Fournier of Nantes proposed erecting a temple consecrated to the Sacred Heart of Jesus as an act of national penance. Alexandre Legentil joined the initiative in January 1871 and organized an entirely private fundraising campaign; the total cost was estimated at seven million francs. The project was approved by the French National Assembly and, after a selection process among 77 proposals, the works officially began on June 16, 1875 under the direction of architect Paul Abadie. Following Abadie's death in 1884, five successive architects continued the work until its completion in 1914. The consecration was postponed by the First World War and was celebrated on October 16, 1919. More than a century after its construction, the building was declared a national historical monument of France on December 8, 2022, after decades of political controversy linked to the events of the Paris Commune of 1871.

🏛️ Architecture

The basilica was designed by Paul Abadie as a free interpretation of Romano-Byzantine architecture, in deliberate contrast to the neo-baroque style of the Palais Garnier. The construction presented considerable technical challenges: the subsoil of the Montmartre hill, traversed by ancient gypsum extraction galleries, required the drilling of 83 wells 30 meters deep, filled with rock and concrete to serve as foundation pillars. The building measures 85 meters in length by 35 in width; the dome reaches 83 meters in height and the bell tower 84 meters. The predominant material is travertine limestone from Château-Landon, extracted in Souppes-sur-Loing, a fine-grained stone that progressively becomes whiter due to the action of rainwater on the calcite. Inside, the mosaic "The Triumph of the Sacred Heart of Jesus," the work of Luc-Olivier Merson and collaborators, was dedicated in 1923; it is composed of 25,000 enameled and gilded pieces covering 475 square meters, ranking among the largest religious mosaics in the world. The organ, built by Aristide Cavaillé-Coll in 1898 for a private château in Biarritz and installed in the temple in 1905, has 109 ranks and 78 stops distributed across four keyboards.

⭐ Key Facts

According to documented records, it is the second most visited tourist attraction in Paris, after the Eiffel Tower. The building was declared a national historical monument of France on December 8, 2022. In the bell tower is "La Savoyarde," the largest bell in France, cast on May 13, 1891 by the Paccard foundry in Annecy-le-Vieux; with a weight of 18,835 kilograms, it is the fifth largest bell in Europe. The church maintains a historical association with Saint Denis of Paris, patron saint of the city, reinforcing its status as a spiritual reference for French Catholics and for pilgrims from different parts of the world who come to Montmartre.
