Tehran, the capital city of Iran and the centre of the province of Tehran, located in north-central Iran at the foot of the Elburz mountain range. Since its establishment as the capital city by Agha Mohammad Khan more than 200 years ago, Tehran has grown from a small city to a major metropolis: situated in an urban region of 14 million inhabitants, Tehran is Iran’s largest city and one of the most populous cities of the world.

Tehran has a hot, arid climate shared by many parts of central Iran. Although the summer is very long, the city enjoys four distinct seasons, and the Elburz mountain range prevents the humidity of the Caspian Sea in the north from reaching the city. 

The Centre of the city is on latitude 35°41′ N and longitude 51°26′ E. Tehran is located on the steep southern slopes of the Elburz mountain range, which traces an arc along the coast of the Caspian Sea in northern Iran. Its highest peak, Mount Damavand (Demavend), has an elevation of more than 18,400 feet (5,600 meters) and is visible from Tehran on clear days. The highest point in Iran, Damavand is also higher than any other peak among the summits to its west in Asia and Europe. Figuring prominently in Persian legend, Damavand holds for Iranians much the same significance as Mount Fuji offers the Japanese. The symbolic significance of this site and its location on the historic east-west trade route (Silk Road) have ensured that this area has been the site of significant settlement for several millennia. Towchal ridge (12,904 feet [3,933 meters]), the site of a popular ski and recreation site linked to the city by a series of cable cars, dominates the city from the north, while the city’s southern reaches extend toward Kavir, a desert located in north-central Iran.

 Even though the city is the meeting point of many ethnic and linguistic groups, it is dominated by the Persian culture and language, as well as the Shi?i branch of Islam, with which the majority of the population identifies
