Basilique du Sacré-Cœur de Montmartre

Perched atop Montmartre, the Basilique du Sacré-Cœur offers sweeping panoramic views over Paris and a solemn, historic interior anchored by its impressive mosaic and white domes. Visitors come for quiet contemplation, photography and the unforgettable city vistas; expect some stair climbs, crowds at the lookout and a mix of tourists and worshippers. Entry to the basilica is free, though the dome and crypt may have separate fees and lines.
