Takht –e- Rostam or Rostam’s Throne is name of a volcanic rock cliff (the highest mountain in the region) and ruins of an ancient Zoroastrian fire temple on it, around 80 km south west of Tehran and close to city of Shahryar.
The temple belongs to Sassanid era (224-651 AD) and consists of two stages, the lower stage on the cliff slope and upper one on the pick. There are remains of some stone chambers which are believed to be fire braziers.
The fire on upper stage was visible from distance of 150 km during clear nights.
According to research the fire, the fire was lit in the stone chamber of the circular area of about hundred and fifty miles in a night that had been exposed.
A platform and a small building at the bottom of the mountain were there. This small building is located in the 15-meter platform and the roof has remained intact, the apex of the dome to the surface is 238 cm and has two entries with the arch-style architecture of Islam.
Archaeologists knew the location of the center of Zoroastrian ceremonies and bed as a place for people to have a great time, besides over the mountain peaks Clergymen and religious people lived.
Takht –e- Rostam has saved its dignity for local people which celebrate some traditional days like 13th day of new year (Sizdah be dar) around it with special ceremonies.
