One of the most famous (and iconic) green walls grows on the roadside face of the Musee du quai Branly, in Paris.

Completed in 2005, the 40 feet tall by 650 foot long vertical garden highlights the work of its creator, Patrick Blanc.  Designed as a living tapestry to reflect the diversity of world cultures housed by the museum, the eye catching green wall, just next to the Eiffel Tower, is arguably the best-known green wall in Europe.
