Farhād Tarāsh — Wikipedia

The Farhād Tarāsh (Persian: فرهاد تراش), or Tarāsh-e Farhād, is a long smoothed rock surface on Mount Behistun in western Iran. Located near the famous Behistun Inscription, its height is around 30 meters and its width is around 200 meters. The retaining wall in front of it is c. 150 meters. The work is registered as a national heritage in Iran, and it's the biggest work of such kind in Iran. The Farhād Tarāsh has sparked interest from medieval geographers including Istakhri (died 957) and Yaqut al-Hamawi (died 1229) to travelers and archaeologists in modern times.
