What is the capital of Iran?
Tehran, located in northern Iran, is the capital and largest city of Iran. It is also the center of the province (ostān) of Tehran, for which it is named. Tehran has grown rapidly since it became the capital of Iran over 200 years ago. The city is located at the foot of the Elbourz Mountains, which gives it a privileged geographical position. It is located on the east-west road along the foothills of the Elbourz, as well as on the roads leading to the oases of central Iran and the basins of Fars.
Tehran is also an important academic and industrial center in Iran. Its industries include the production of textiles, cement, foodstuffs and medicines. There is also an oil refinery near the city. The city has a metro, which currently has 7 lines, as well as a dense highway system.
Tehran has a population of about 9 million in 2015, and the metropolitan area has more than 15 million people. This rapid growth is mainly due to improved living conditions and the attraction of people from the provinces.
