The word prompt from Frank at Dutch goes the Photo: Wall
A few years ago we went to Madrid and it is here I found this wall.
That’s not a wall I hear you say. It’s a garden.
Well here’s the wall
It is vertical garden designed and built by Patrick Blanc. An impressive approx 24 meters tall green wall with 250 different species of plants that survive without soil. A living piece of art in the CaixaForum square.
