Tehran is the capital of Iran and Tehran Province. With a population of around 8.7 million in the city and 15 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, and has the third-largest metropolitan area in the Middle East (surpassed by Cairo and Istanbul). It is ranked 24th in the world by the population of its metropolitan area.
Tehran is a cosmopolitan city, with great museums, parks, restaurants, and warm friendly people. It deserves at least a few days of your Iranian itinerary.
Tehran has also earned itself the rather unenviable reputation as a smog-filled, traffic-clogged and featureless sprawl of concrete bursting at the seams with 14 million residents. But you can also find an endless number of nice and cosy places in and around the city – if you know where to look. Tehran is also a city of parks and possesses more than 800 of them, all well-kept. The city is nearly a mile high above sea level and as a result is cooler than other cities in the middle east. Summer temperatures are around 36°C or about 95-100°F. The air tends to be very dry.
A combination of factors make Tehran a pleasant place to visit: The dry climate which is constantly cool (at least in the evenings), the proximity of the mountains, the parks and gardens where flowers blossom all through the year, the alleys of trees in the avenues or even smaller streets, and even the water that runs down from the upper city along deep and wide gutters which look like small rivers during spring. The Alborz range to the north of Tehran, which hosts the highest peak in Iran, provides fantastic conditions for ski lovers in the winter. In winter, the mountain hotels and ski-clubs at Shemshak, and Dizine are full several days a week. Some specialist skiers consider the snow value in northern Tehran to be some of the best in the world.
Tehran is home to many historical collections, including the royal complexes of Golestan, Sa’dabad, and Niavaran, where the two last dynasties of the former Imperial State of Iran were seated. Tehran’s most famous landmarks include the Azadi Tower, a memorial built under the reign of Mohammad Reza Shah of the Pahlavi dynasty in 1971 to mark the 2,500th year of the foundation of the Imperial State of Iran, and the Milad Tower, the world’s sixth-tallest self-supporting tower which was completed in 2007. The Tabiat Bridge, a newly built landmark, was completed in 2014.
The majority of the population of Tehran are Persian-speaking people, and roughly 99% of the population understand and speak Persian, but there are large populations of other ethno-linguistic groups who live in Tehran and speak Persian as a second language.
Tehran has an international airport (Imam Khomeini Airport), a domestic airport (Mehrabad Airport), a central railway station, the rapid transit system of Tehran Metro, a bus rapid transit system, trolleybuses, and a large network of highways.
October 6 is marked as Tehran Day based on a 2016 decision by members of the City Council, celebrating the day when the city was officially chosen as the capital of Iran by the Qajar dynasty back in 1907.
