CaixaForum Vertical Garden

The CaixaForum square, with its impressive architectonical design, boasts a pond and a green, fresh, extraordinary wall forming a vertical garden which takes up the entire wall of a side building.

Based on his own theory that “plants do not need soil; they just need water, minerals, light, and carbon dioxide,” Patrick Blanc built an impressive 78 -foot tall green wall with 250 different species of plants that survive without soil and which give the appearance of a living piece of art.
