The Bosco Verticale – “The Vertical Forest” was one of the most unique buildings I had ever seen in Milan. There were 900 trees, 5,000 shrubs and 11,000 floral plants that had been imbedded against the two towers. The towers were built in this style, to reduce smog and increase oxygen levels.
What a brilliant way of connecting nature and the city!
