Exhibits of the museum show the history and culture of Mongols from ages as early as the Stone Age and up to the modern days. Among 15 thousand exhibits of the museum are carpet and silk items of the Xiongnu period and leather boots of a Mongolian soldier of that time.
 The 1st floor has some interesting exhibits on petroglyphs, deer stones (stone sculptures of reindeer and other animals) and burial sites from the Xiongnu and Uyghur eras. The 2nd floor houses an outstanding collection of costumes, hats and jewellery, representing most of Mongolia's ethnic groups.

The 3rd floor is a must-see for fans of the Mongol horde. The collection includes real examples of 12th century Mongol Armour, and correspondence between Pope Innocent IV and Guyuk Khaan. Written in Latin and Persian and dated November 13, 1246, it bears the khaan's seal. There is also a display of traditional Mongolian culture with, among other things, a furnished Ger, traditional farming and domestic implements, saddles and musical instruments.
