The Basilique du Sacré-Cœur is a famous Roman Catholic church located at the highest point in Paris, Montmartre. Completed in 1914 and consecrated in 1919, it was built as a symbol of national reconciliation after France's defeat in the Franco-Prussian War. Designed by architect Paul Abadie, its Romano-Byzantine style features a striking white travertine stone façade, which remains luminous even in bad weather. Today, Sacré-Cœur remains one of Paris' most visited landmarks.
