The Sacré-Coeur (Sacred Heart) Basilica overlooks the hill of Montmartre, on the right bank of the Seine. Its construction was driven by a vow. In 1871, after the defeat of France against Prussia and the economic and morale crisis that followed, two men, Alexandre Legentil and Hubert Rohault de Fleury, made a vow to the Sacred Heart of Jesus to raise a shrine to it. In 1872, they persuaded the new Archbishop of Paris, Mgr. Guibert, to support their “National Vow to obtain the deliverance of the Sovereign Pontiff and the salvation of France”. The following year, the National Assembly, with its conservative majority, declared their National Vow to be of public service.
