In top of the rocky mountain of Rahmat in the plain of Marvdasht, the ruins of Takht-e-Jamshid palace are pre-eminent. Construction of these palaces started at the time of Darius I (521 BC) and was not completed in less than a period of 150 years. Takht-e-Jamshid is registered as a World Heritage Site by UNESCO.
The entrance of the complex is formed by a two-ramp stairway composed of 110 rather wide and short steps. On top of the stairways is the main entrance or “The Great Gate”, marked by two statues of a bull with a human head and a pair of wings. There are two exits, one to the south and the other to the east. The south exit or gate connects to the Apadana Palace.
