Tagh-e Bostan orTaq-i-Bustan is a series of large rock relief from the era of Sassanid Empire of Persia, the Iranian dynasty which ruled western Asia from 226 to 650 AD. This example of Sassanid art is located 5 km from the city of Kermanshah in western Iran. It is located in the heart of the Zagros mountains, enduring almost 1700 years of wind and rain.
The carvings, some of the finest and best-preserved examples of Persian sculpture under the Sassanids, include representations of the investitures of Ardashir II (379–383) and Shapur III (383–388). Like other Sassanid symbols, Taq-e Bostan and its relief patterns accentuate power, religious tendencies, glory, honor, the vastness of the court, game and fighting spirit, festivity, joy, and rejoicing.
Sassanid kings chose a beautiful setting for their rock reliefs along an ancient Silk Road caravan route way point and camp ground. The reliefs are adjacent a sacred spring that empties into a large reflecting pool at the base of a mountain cliff.
Taq-e Bostan and its rock relief are one of 30 surviving Sassanid relics in the chest of Zagros mountains.
