Built on the summit of Montmartre, the highest hill in Paris, Sacré-Cœur towers above the city's rooftops. Hike up the hill's cobblestone streets—or take the funicular railway—to get a close-up look at one of France's most elegant architectural achievements. The basilica's soaring white domes hide a marvelous sanctuary within. A neo-Byzantine mosaic of Christ with arms spread wide covers the semispheric apse. After you take in the splendor of the interior, stop and sit on the steps outside for some awe-inspiring panoramic views of Paris.
