Art Nouveau design

These famed entrances designed by Hector Guimard were surrounded in talk and not a little controversy in 1900.  The most elaborate were those with glass canopies, of which three still exist.  

Guimard's design above can be seen all over Paris, and there are 80 of this style with cast-iron balustrades decorated in plant-like motifs still remaining today.  The orange light globes sit atop ornate cast-iron supports in the form of plant stems.  Typical of the Art Nouveau style, the entire design is quite "organic."
