The first western gardens were those in the Mediterranean basin. There in the desert areas stretching from North Africa to the valleys of the Euphrates, the so-called cradle of civilization, where plants were first grown for crops by settled communities, garden enclosures were also constructed. Gardens emphasized the contrast between two separate worlds: the outer one where nature remained awe-inspiringly in control and an inner artificially created sanctuary, a refuge for man and plants from the burning desert, where shade trees and cool canals refreshed the spirit and ensured growth.
