Dependent on the church of Sainte-Geneviève, which it was destined to survive, is the church of St. Stephen-of-the-Mount. Among the wonders of Saint-Étienne-du-Mont is the tomb of Sainte Geneviève, whose relics, patroness saint of Paris as she was, were burnt in 1793 by the Paris Commune in the Place de Grève. During the fête of Sainte Geneviève, from the 3rd to the 11th of January, the church is crowded with pilgrims from the Paris suburbs to the number, it is calculated, of more than one hundred thousand. In the chapel immediately facing the altar stands a monument which contains the heart of Monseigneur Sibour, Archbishop of Paris, assassinated on the 3rd of January, 1857, in this very church, when he was opening the nine days’ service in honour of Sainte Geneviève, by a priest whom he had interdicted. The predecessor of Monseigneur Sibour, Monseigneur Affre, was shot dead by the insurgents of June, 1848, when exhorting them from a barricade to cease fighting. His successor, Monseigneur Darboy, was put to death with the other hostages whom the Paris Commune in 1871 had taken with the view of securing for the Communards made prisoners by the troops the character of prisoners of war.
