Kabul is the capital and largest city of Afghanistan, located in the eastern section of the country. It is also the capital of Kabul Province and is situated at an elevation of roughly 1,790 meters (5,873 feet) above sea level, making it one of the highest capital cities in the world. The city is situated in a narrow valley between the Hindu Kush mountains and along the Kabul River. Kabul serves as the nation's cultural and economic hub. It has a history that dates back over 3,500 years, with its establishment as a city for many centuries. Despite the recent conflicts, Kabul retains architectural evidence of its long history, with old forts, palaces, and bazaars scattered amidst the urban sprawl. The city has seen rapid urbanization and population growth since the beginning of the 2000s. Kabul's population is diverse, with a mix of ethnic groups including Pashtun, Tajik, Hazara, and Uzbek, which is reflected in the city's multiple cultural facets. Since the end of Taliban rule, the city's infrastructure has improved, but it still faces challenges such as security concerns.
