The Basilica of the Sacred Heart of Paris, commonly known as Sacré-Cœur Basilica and often simply Sacré-Cœur pronounced is a Roman Catholic church and minor basilica, dedicated to the Sacred Heart of Jesus, in Paris, France. A popular landmark, the basilica is located at the summit of the butte Montmartre, the highest point in the city. Sacré-Cœur is a double monument, political and cultural, both a national penance for the excesses of the Second Empire and socialist Paris Commune of 1871 crowning its most rebellious neighborhood, and an embodiment of conservative moral order, publicly dedicated to the Sacred Heart of Jesus, which was an increasingly popular vision of a loving and sympathetic Christ.
The Sacré-Cœur Basilica was designed by Paul Abadie. Construction began in 1875 and was finished in 1914. It was consecrated after the end of World War I in 1919.
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 The law was rescinded, but the Basilica was saved by a technicality and the bill was not reintroduced in the next session.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 Palais 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
Construction costs, estimated at 7 million French francs and drawn entirely from private donations, were expended before any above-ground visible structure was to be seen. A provisional chapel was consecrated 3 March 1876, and pilgrimage donations quickly became the mainstay of funding. Donations were encouraged by the expedient of permitting donors to "purchase" individual columns or other features as small as a brick. It was declared by the National Assembly that the state had the ultimate responsibility for funding.
Muted echoes of the Basilica's "tortured history" are still heard, geographer David Harvey has noted. In February 1971 demonstrators pursued by the police took refuge in the Basilica and called upon their radical comrades to join them in occupying a church "built upon the bodies of communards in order to efface that red flag that had for too long floated over Paris" as their leaflets expressed it.
