'Arch of stone')[1] 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 CE.
The site has been turned into an archaeological park and a series of late Sassanian and Islamic column capitals have been brought together (some found at Taq Bostan, others at Mount Behistun and Kermanshah).
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 a historic Silk Road caravan route waypoint and campground.
