The Basilica of the Sacred Heart of Paris (or Sacré-Cœur Basilica) sits on top of Montmartre Hill, the highest point in the city of Paris. It’s one of the architectural highlights, taking inspiration from the Hagia Sophia and St. Mark’s Basilica in Venice. Since its completion in 1914, it’s been one of Paris’s must-see sights and is visited by tourists from all around the world.
