Located just five kilometers from the Iranian city of Kermanshah, Taq-e Bostan, or arch of the garden, is a UNESCO declared Heritage site from the Sassanid era in the Zagros Mountains.
Taq-e Bostan contains a series of the finest surviving large rock reliefs, which are some of the best-preserved examples of Persian Sassanid era sculptures.
The area also serves as a lovely picnic place for domestic and foreign tourists who come in large numbers to spend a holiday in this pleasant spot.
