Taq-e Bostan means “Arch of the Garden” or “Arch made by stone” is a site with a series of large rock reliefs from the era of the Sassanid Empire of Persia (Iran), carved around the 4th century AD.
This example of Persian Sassanid art is located 5 km from the city center of Kermanshah. It is located in the heart of the Zagros mountains, where it has endured almost 1,700 years of wind and rain. Originally, several sources were visible next to and below the reliefs and arches, some of which are now covered. Sources next to the reliefs still feed a large basin in front of the rock. The site has been turned into an archaeological park and a series of late Sasanian and Islamic column capitals have been brought together (some found at Taq Bostan, others at Bisutun and Kermanshah).
