The Sacre Coeur
Contrary to what many visitors believe, the Sacre Coeur is not very old. It was built after the 19th century French Cold Civil War. There are buildings in the United States that are far older than this Parisian landmark.
It is perched on a hill in Montmartre not unlike a garrison keeping an eye on all below it.
Its highest point is higher than the highest point of the Eiffel Tower.
Thus has it imposed itself as a symbol of Paris as much as La Dame de Fer and the Arc de Triomphe, always used for an establishing shot by every movie producer as the shortest way to tell viewers where the story is unfolding.
