On October 16, 1919, the Sacré-Coeur church in Montmartre was consecrated by Cardinal Vico and elevated to the rank of basilica, after 44 years of construction. Erected on the heights of the Butte Montmartre, this Romanesque-Byzantine religious edifice still fascinates as much as it horrifies some Parisians, who consider it to have been "built on the blood of the Communards".
