Basilique du Sacré-Cœur

The Basilica of the Sacred Heart of Jesus of Paris, commonly known as Sacré-Cœur Basilica (French: Basilique du Sacré-Cœur, pronounced [sakʁe kœʁ]), is a Roman Catholic church and minor basilica, dedicated to the Sacred Heart of Jesus.

The inspiration for the Basilica originated in the wake of the division in French society that arose in the decades following French Revolution, between devout Catholics and legitimist royalists on one side, and democrats, secularists, socialists and radicals on the other. This schism became particularly pronounced after the Franco-Prussian War and the ensuing uprising of the Paris Commune of 1870-71. Montmartre had been the site of the Commune's first insurrection, and many hard-core communards were forever entombed in the subterranean galleries of former gypsum mines where they had retreated, by explosives detonated at the entrances by the Army of Versailles. Hostages had been executed on both sides, and the Communards had executed Georges Darboy, Archbishop of Paris, who became a martyr for the resurgent Catholic Church. His successor Guibert, climbing the Butte Montmartre in October 1872, was reported to have had a vision, as clouds dispersed over the panorama: "It is here, it is here where the martyrs are, it is here that the Sacred Heart must reign so that it can beckon all to come".

In the moment of inertia following the resignation of the government of Adolphe Thiers, 24 May 1873, François Pie, bishop of Poitiers, expressed the national yearning for spiritual renewal— "the hour of the Church has come"— that would be expressed through the "Government of Moral Order" of the Third Republic, which linked Catholic institutions with secular ones, in "a project of religious and national renewal, the main features of which were the restoration of monarchy and the defense of Rome within a cultural framework of official piety", of which Sacré-Cœur is the chief lasting triumphalist monument.

The decree voting its construction as a "matter of public utility", 24 July, followed close on Thiers' resignation. The project was expressed by the Church as a National Vow (Voeu national) and financial support came from parishes throughout France. The dedicatory inscription records the Basilica as the accomplishment of a vow by Alexandre Legentil and Hubert Rohault de Fleury, ratified by Joseph-Hippolyte Guibert, Archbishop of Paris. The project took many years to complete.

A law of public utility was passed to seize land at the summit of Montmartre for the construction of the basilica. Architect Paul Abadie designed the basilica after winning a competition over 77 other architects. With delays in assembling the property, the foundation stone was finally laid 16 June 1875. Passionate debates concerning the Basilica were raised in the Conseil Municipal in 1880, where the Basilica was called "an incessant provocation to civil war" and it was debated whether to rescind the law of 1873 granting property rights, an impracticable proposition. The matter reached the Chamber of Deputies in the summer of 1882, in which the Basilica was defended by Archbishop Guibert while Georges Clemenceau argued that it sought to stigmatise the Revolution. The law was rescinded, but the Basilica was saved by a technicality and the bill was not reintroduced in the next session. A further attempt to halt the construction was defeated in 1897, by which time the interior was substantially complete and had been open for services for six years.

The overall style of the structure shows a free interpretation of Romano-Byzantine features, an unusual architectural vocabulary at the time, which was a conscious reaction against the neo-Baroque excesses of the Opéra Garnier, which was cited in the competition. Many design elements of the basilica symbolise nationalist themes: the portico, with its three arches, is adorned by two equestrian statues of French national saints Joan of Arc (1927) and King Saint Louis IX, both executed in bronze by Hippolyte Lefebvre; and the nineteen-ton Savoyarde bell (one of the world's heaviest), cast in 1895 in Annecy, alludes to the annexation of Savoy in 1860.

Abadie died not long after the foundation had been laid, in 1884, and five architects continued with the work: Honoré Daumet (1884–1886), Jean-Charles Laisné (1886–1891), Henri-Pierre-Marie Rauline (1891–1904), Lucien Magne (1904–1916), and Jean-Louis Hulot (1916–1924). The Basilica was not completed until 1914, when war intervened; the basilica was formally dedicated in 1919, after World War I, when its national symbolism had shifted. Consecration of the basilica was delayed until after World War I.

Sacré-Cœur is built of travertine stone quarried in Château-Landon (Seine-et-Marne), France. This stone constantly exudes calcite, which ensures that the basilica remains white even with weathering and pollution.

A mosaic in the apse, entitled Christ in Majesty, is among the largest in the world. The basilica complex includes a garden for meditation, with a fountain. The top of the dome is open to tourists and affords a spectacular panoramic view of the city of Paris, which is mostly to the south of the basilica.

The basilica is home to a large and very fine pipe organ built by Aristide Cavaillé-Coll for a private home in Biarritz, composed of 109 ranks and 78 speaking stops spread across four 61-note manuals and the 32-note pedalboard (unusual before the turn of the century; the standard of the day was 56 and 30), spread across three expressive divisions (also unusual for the time, even in large organs); the organ was ahead of its time, containing multiple expressive divisions and giving the performer considerable advantages over other even larger instruments of the day.
