Fin Garden located in Kashan, Iran, is a historical Persian garden. The layout for this kind of garden dates back to the time of Cyrus the Great. One of the most prominent features of them is a principle of "four gardens" – when a square garden is divided into four parts by waterways. They represent the harmony of four Zoroastrian elements – sky, earth, water, and plants.
