Ulaanbaatar, the capital of Mongolia resides on the banks of river Tuul. It was founded in 1639 as the center of Buddhism and has since grown to reflect a mix of ancient traditions, Buddhist rituals, and modern commerce and trade. It is the undisputed political, economic, and cultural hub of Mongolia. The capital is administrated in six districts (Sukhbaatar, Khan-Uul, Chingeltei, and Bayangol) and three satellite towns of Nalaikh, Baga Khangai, and Baganuur.
As of 2021, Ulaanbaatar's population was estimated at 1.615.000 residents. The first foundation stone of the future capital of Mongolia dates to 1639 at a locale in present-day Arkhangai aimag.
