The Basilica of the Sacred Heart of Paris, commonly known as Sacré-Cœur Basilica and often simply Sacré-Cœur, is a Roman Catholic church and minor basilica in Paris, France, dedicated to the Sacred Heart of Jesus.
Sacré-Cœur Basilica is located at the summit of the butte Montmartre, the highest point in the city. It is a popular landmark, and the second-most visited monument in Paris. Sacré-Cœur Basilica has maintained a perpetual adoration of the Holy Eucharist since 1885. The basilica was designed by Paul Abadie. Construction began in 1875 and was completed in 1914. The basilica was consecrated after the end of World War I in 1919.
It is considered as both a political and cultural monument, representing a national penance for the defeat of France in the 1870 Franco-Prussian War and for the actions of the socialist Paris Commune of 1871. Sacré-Cœur Basilica was built in a neighborhood which witnessed significant events by the Paris Commune of 1871.
