This is a little off topic, but it reflects classic Art Nouveau industrial design and another of my passions, Paris, especially Montmartre. It's the Guimard-designed entrance to Abbesses Métro station in the 18th arrondissement at the foot of the hill atop which stands the magnificent Sacré Coeur.
Abbesses is the deepest station on the Métro because it's built on the hill ('butte', literally mound) of Montmartre.
This is one of only two Guimard original entrances that remain (the other is at Porte Dauphine). It was originally at Hôtel de Ville and was moved to Abbesses in 1970.
The reason I've published this 'photo separately here is that I like it and quite by chance I captured a young couple snogging as they part from each other. How very Parisian.
And by happy chance some years later I was wandering around Mexico City and came across a clearly Guimard-inspired metro station!
