The Sacré- Cœur (Sacred Heart) Basilica is located at the top of Montmartre hill, the highest point in Paris. If you add the 83 metres of its central cupola, you get a monument that can be seen from very far away. The white hues of the exterior walls of the basilica are due to the use of limestone which whitens in contact with rainwater. Extracted in Souppes-sur-Loing, in Seine-et-Marne, the very hard, fine-grained stones of Château-Landon further enhance the visibility of the building. The Montmartre funicular provides access to the Sacré-Cœur from Saint-Pierre’s square without having to climb the 222 steps along Foyatier street.
