The Persian Garden, which was awarded the World Cultural Heritage in 2011, consists of nine gardens distributed in nine provinces. These nine gardens were built in different periods, and the earliest can be traced back to the 6th century BC. The main design concept of Persian gardens highlights the symbolic images of the four elements of Eden and Zoroastrianism-sky, water, earth and plants. All gardens are divided into four parts, and water plays an important role in the irrigation and decoration of gardens. Terraces, pavilions, walls and sophisticated water flow irrigation system are the important features of gardens. Persian gardens have influenced Indian and Spanish garden art.
