Founded in the 4th century BC by the Sassanid ruler, Bahram IV, it is one of the oldest cities in Iran. At the foot of the Zagros Mountains, the city is built at 1420 meters above sea level. Kermânchâh enjoys a very moderate continental climate. The average temperature generally does not exceed 22 ° C during the warmer months.

Bisotoun and Tâgh Boustân are the two major sites to visit. The inscription of Bisotoun is a monumental and illustrated inscription describing the conquests of Darius I in three languages: Old Persian, Elamite and Akkadian. The inscription, approximately 15 meters high and 25 meters wide, is located 100 meters above the ancient road linking the capitals of Babylon in Babylonia and Ecbatana of the Median Empire.

Tâgh Boustân is a Sassanid site of the 4th and 6th centuries, comprising two sculpted caves and a bas-relief, next to a spring. It is located at the foot of a mountain of the Zagros chain at the exit of the city. The function of the site is unknown, but the presence of an ancient enclosure delineating a large enclosure, still partially visible today, and representations of royal hunts suggest that it was a garden or a Hunting royal.

It is also advisable to go to the Temple of Anahita, a spectacular monument, which will offer you the opportunity to contemplate the largest architectural complex dedicated to the goddess Anahita.
