The Basilica of the Sacred Heart, or Basilique du Sacré-Coeur, perched at the very top of Butte de Montmartre (Montmartre Hill), was built from contributions pledged by Parisian Catholics as an act of contrition after the Franco-Prussian War of 1870-71. Construction began in 1873, but the basilica was not consecrated until 1919. The basilica's domes are a well-loved part of the Parisian skyline.
A 234-step climb up narrow spiral staircases takes you up to the dome, which affords one of Paris' most spectacular panoramas. It is, however, outside on the steps where the action takes place - lovers, buskers, locals and foreigners all converge to take in the vistas and each other.
