The Walled Garden owes its inspiration to the great Indo-Persian gardens of antiquity. Like the ancient gardens, the Walled Garden is divided into quadrants by waterways and bordered by crenellated walls anchored by octagonal towers. The Indo-Persian walled garden was intended to mimic a paradise on earth and thus had features inspired by religious descriptions of paradise. Biblical descriptions of Eden include four rivers (Pishon, Gihon, Tigris and the Euphrates) and two great trees (the Tree of Life and the Tree of the Knowledge of Good and Evil). Islam describes paradise, or Jannah, and includes similar elements: four rivers of life (water, milk, honey and wine), and the Tree of Life.
