The CaixaForum plaza, a striking architectural intervention, is accompanied by a pond and a fresh and lush plant wall, like a vertical garden, which occupies the entire party wall of a side building. It is the first one to be carried out in Spain and the one with the largest continuous surface area in the world.
The French botanist Patrick Blanc, inventor of this technique, designed this vertical garden based on his axiom “plants do not need soil, only water, minerals, light and carbon dioxide”. Following this conviction, he built a spectacular 24-meter high vegetal wall with 250 different species that survive without soil and resemble a living painting. More than 15,000 plants cover an area of 460m2.
