is the provincial capital of Mazandaran and former capital of Iran (for a short period), located in the north of Iran, between the northern slopes of the Alborz Mountains and southern coast of the Caspian Sea.Sari is the largest and most populous city of Mazandaran.Sari Rail Station and most of the streets and governmental buildings date from that era.During World War II the Soviet army occupied the city, but left it after the war.Han Way, who visited Saru in 1734, makes mention of four ancient Magian temples as still standing then, built in the form of several rotundas, each thirty feet in diameter, and about 120 in height.
After the Safavid dynasty fell and until the rise of Agha Mohammad Khan to power there, is no evidence of any notable events in Sari.
Out of four, one of the rotunda is still standing since the rest were overturned by an earthquake.
This and other remains of similar buildings, bear the names of Fereydun, Salm, Tur, and other mythical figures, whose celebrity had been established about 2000 years prior to their erection.
According to Arrian, this was the largest city of Hyrcania.
The term means "the yellow city" and it was given to it because of the great number of orange, lemon, and other fruit trees that grew in the outskirts of that city.
Espahbod Tous-e Nouzar (great-grandson of Fereydun) systematically founded it to remain as family monument.
