Green roofs are not a modern invention. They have been built since antiquity, if we only think of the Semiramis Garden also known as The Hanging Gardens of Babylon, built between 605-562 BC, by King Nebuchadnezzar II. They stretched over 15,000 m2 and had four distinct floors, the last one rising up to 77 meters. Vegetation and trees used to provide effective protection against heat and sunlight.
Over time, there have been also countries where people have adapted their needs to the existing resources. In Iceland, for example, due to the lack of building materials, green roofs used to be a very common occurrence.
Their popularity grew worldwide in the 20th century, when shops and malls started to set up real green parks on their roofs.
